Network > Routing > Routing Profiles > BGP

Create BGP routing profiles to efficiently configure BGP for the logical router.

For a logical router, use BGP routing profiles to efficiently apply configuration to BGP peer groups, peers, or redistribution rules. For example, you can apply a Timer Profile, Authentication Profile, and BGP Filtering Profiles to a BGP peer group or a peer. You can apply an Address Family (AFI) profile for IPv4 and for IPv6 to a peer group or peer. You can apply a Redistribution profile for IPv4 and for IPv6 to BGP redistribution.

BGP Routing Profiles	Description
BGP Auth Profile
Name	Enter a name for the Authentication profile (maximum of 63 characters). The name must start with an alphanumeric character, underscore (_), or hyphen (-), and contain zero or more alphanumeric characters, underscore (_) or hyphen(-). No dot (.) or space is allowed.
Secret	Enter the Secret and Confirm Secret. The Secret is used as a key in MD5 authentication.
BGP Timer Profile
Name	Enter a name for the Timers profile (maximum of 63 characters). The name must start with an alphanumeric character, underscore (_), or hyphen (-), and contain zero or more alphanumeric characters, underscore (_) or hyphen(-). No dot (.) or space is allowed.
Keep Alive Interval (sec)	Enter the interval, in seconds, after which routes from the peer are suppressed according to the Hold Time setting (range is 0 to 1,200; default is 30).
Hold Time (sec)	Enter the length of time, in seconds, that may elapse between successive Keepalive or Update messages from the peer before the peer connection is closed (range is 3 to 3,600; default is 90).
Reconnect Retry Interval	Enter the number of seconds to wait in Idle state before retrying to connect to the peer (range is 1 to 3,600; default is 15).
Open Delay Time (sec)	Enter the number of seconds of delay between opening the TCP connection to the peer and sending the first BGP Open message to establish a BGP connection (range is 0 to 240; default is 0).
Minimum Route Advertise Interval (sec)	Enter the minimum about of time, in seconds, that must occur between two successive Update messages (that a BGP speaker [the firewall] sends to a BGP peer) that advertise routes or withdrawal of routes (range is 1 to 600; default is 30).
BGP Address Family Profile
Name	Enter a name for the Address Family Identifier (AFI) profile (maximum of 63 characters). The name must start with an alphanumeric character, underscore (_), or hyphen (-), and contain zero or more alphanumeric characters, underscore (_) or hyphen(-). No dot (.) or space is allowed.
AFI	Select the type of AFI profile (IPv4 or IPv6).
unicast / multicast	Select the Subsequent Address Family Identifier (SAFI) type.
Enable SAFI	Select for the profile to enable the unicast and/or multicast SAFI. At least one SAFI must be enabled for the BGP profile to be valid; you can enable both SAFIs.
Soft reconfiguration of peer with stored routes	Select to cause the firewall to perform a soft reset of itself after settings of any of its BGP peers are updated. (Default is enabled.)
Advertise all paths to peers	Advertise all paths to neighbors in order to preserve multipath capabilities inside a network.
Advertise the bestpath for each neighboring AS	Enable to ensure that BGP advertises the best path for each neighboring AS, and not a generic path for all autonomous systems. Disable this if you want to advertise the same path to all autonomous systems.
Override ASNs in outbound updates if AS-Path equals Remote-AS	You might use the BGP AS override feature if you have multiple sites belonging to the same AS (AS 64512, for example) and there is another AS between them. A router between the two sites receives an Update advertising a route that can access AS 64512. To avoid the second site dropping the Update because it is also in AS 64512, the intermediate router replaces AS 64512 with its own ASN, AS 64522, for example.
Route Reflector Client	Enable to make the BGP peers a BGP Route Reflector Client in an iBGP network.
Originate Default Route	Select to advertise all default routes. Disable if you want to advertise only routes to specific destination.
Default Originate Route-Map	Apply a route map to the Originate Default Route field, which allows you to specify the types of default routes you want to advertise.
Allow AS in	Specify whether to allow routes that include the firewall’s own autonomous system (AS) number: Origin—Accept routes even if the firewall’s own AS is present in the AS_PATH. Occurrence—Number of times the firewall’s own AS can be in an AS_PATH. None—(default setting) No action taken.
Number Prefixes	Enter the maximum number of prefixes to accept from peer; range is 1 to 4,294,967,295; default is 1,000.
Threshold (%)	Enter the threshold percentage of the maximum number of prefixes. If the peer advertises more than the threshold, the firewall takes the specified Action (warning or restart). Range is 1 to 100.
Action	Specify the action the firewall takes on the BGP connection after the maximum number of prefixes is exceeded: Warning Only message in logs or Restart the BGP peer connection.
Next Hop	Select the next hop: None—Original next hop is preserved. Self—Disable next-hop calculation and advertise routes with local next-hop. Self Force—Force set the next hop to self for the reflected routes.
Remove Private AS	To have BGP remove private AS numbers form the AS_PATH attribute in Updates that the firewall sends to a peer in another AS, select one of the following: All—Remove all private AS numbers. Replace AS—Replace all private AS numbers with the firewall’s AS number. None—(default setting) No action taken.
Send Community	Select the type of BGP community attribute to send in outbound Update messages: All—Send all communities. Both—Send standard and extended communities. Extended—Send extended communities. Large—Send large communities. Standard—Send standard communities. None—Do not send any communities.
ORF List	Advertise the ability of the peer group or peer to send a prefix list and/or receive a prefix list to implement outbound route filtering (ORF) at the source, and thereby minimize sending or receiving unwanted prefixes in Updates. Select one of the following: none—(default setting) The peer group or peer (where this AFI profile is applied) has no ORF capability. both—Advertise that the peer group or peer can send and prefix list and receive a prefix list to implement ORF. receive—Advertise that the peer group or peer can receive a prefix list to implement ORF. The local peer receives the remote peer’s ORF capability and prefix list, which it implements as an outbound route filter. send—Advertise that the peer group or peer can send a prefix list to implement ORF. The remote peer (with receive capability) receives the ORF capability and implements the prefix list it received as an outbound route filter when advertising routes to the sender. Implement ORF by doing the following: Specify ORF capability in the Address Family profile. For a peer group or peer that is a sender, create a prefix list containing the set of prefixes the peer group/peer wants to receive. Create a BGP Filtering profile and in the Inbound Prefix List, select the prefix list you created. For the BGP peer group, select the Address Family profile you created to apply it to the peer group. In the case of the sender, also select the Filtering Profile you created (which indicates the prefix list). If the peer group or peer is an ORF receiver only, it does not need the Filtering Profile; it needs only the Address Family profile to indicate ORF receive capability.
BGP Dampening Profile
Name	Enter a name for the Dampening profile (maximum of 63 characters). The name must start with an alphanumeric character, underscore (_), or hyphen (-), and contain zero or more alphanumeric characters, underscore (_) or hyphen(-). No dot (.) or space is allowed.
Description	Enter a description for the Dampening profile.
Suppress Limit	Enter the suppress value (cumulative value of the penalties for flapping), at which point all the routes coming from a peer are dampened. Range is 1 to 20,000; default is 2,000.
Reuse Limit	Enter value that controls when a route can be reused based on the procedure described for Half Life; range is 1 to 20,000; default is 750.
Half Life (min)	Enter the number of minutes for the half-life time to control the stability metric (penalty) applied to a flapping route. Range is 1 to 45; default is 15. The stability metric starts at 1,000. After a penalized route stabilizes, the Half Life timer counts down until it expires, at which point the next stability metric applied to the router is only half of the previous value (500). Successive cuts continue until the stability metric is less than half of the Reuse Limit, and then the stability metric is removed from the router.
Maximum Suppress Time (min)	Enter the maximum number of minutes a route can be suppressed, regardless of how unstable it has been. Range is 1 to 255; default is 60.
BGP Redistribution Profile
Name	Enter a name for the Redistribution profile (maximum of 63 characters). The name must start with an alphanumeric character, underscore (_), or hyphen (-), and contain zero or more alphanumeric characters, underscore (_) or hyphen(-). No dot (.) or space is allowed.

Otherwise, the Metric configured on this redistribution profile is applied to the redistributed route.
BGP Filtering Profile
Name	Enter a name for the BGP Filtering profile (maximum of 63 characters). The name must start with an alphanumeric character, underscore (_), or hyphen (-), and contain zero or more alphanumeric characters, underscore (_) or hyphen(-). No dot (.) or space is allowed.
Description	Enter a description for the BGP Filtering profile.
AFI	Select IPv4 or IPv6 Address Family Identifier to specify which type of route is filtered.
Unicast Inbound Filter List	Select an AS Path access list or create a new one to specify that, when receiving routes from peer, only routes with the same AS Path are imported from the peer group or peer, meaning added to the local BGP RIB.

Conditional Advertisement—Exist—Exist Map	Select or create a route map to specify the match criteria for the conditional advertisement. If these routes exist in the local BGP RIB, the routes specified by the Advertise Map are advertised. Only the Match portion of the route map in this field takes effect; the Set portion is ignored.
Conditional Advertisement—Exist—Advertise Map	Select or create a route map to specify the routes to advertise in the event that the condition is met (routes from the Exist Map exist in the local BGP RIB). Only the Match portion of the route map in this field takes effect; the Set portion is ignored.
