Enable BGP for the logical router.

Assign a Router ID to BGP for the logical router, which is typically an IPv4 address to ensure the Router ID is unique.

Assign the local autonomous system (AS) to which the logical router belongs based on the Router ID (range for a 2-byte or 4-byte AS number is to 1 to 4,294,967,295).

Select a BFD profile to apply to BGP globally. Default is

None (Disable BFD)

.

Select to cause the firewall to drop an incoming Update message from an EBGP peer that does not list the EBGP peer’s own AS number as the first AS number in the AS_PATH attribute. (Enabled by default.)

Specify the default local preference that can be used to determine preferences among different paths to the same destination; range is 0 to 4,294,967,295; default is 100.

Enable if you configured ECMP and you want to run ECMP over multiple BGP autonomous systems.

Fast failover of EBGP is enabled by default. Disable EBGP fast failover if it causes the firewall to unnecessarily withdraw BGP routes.

Enables graceful restart for BGP so that packet forwarding is not disrupted during a BGP restart (enabled by default).

Specify the length of time, in seconds, that a route can stay in the stale state (range is 1 to 3,600; default is 120).

Specify the maximum length of time, in seconds, that the local device accepts as a grace period restart time for peer devices (range is 1 to 3,600; default is 120).

Select to choose paths from neighbors in different autonomous systems; default is disabled. The Multi-Exit Discriminator (MED) is an external metric that lets neighbors know about the preferred path into an AS. A lower value is preferred over a higher value.

Select to choose between routes that are advertised by IBGP peers (BGP peers in the same AS). Default is enabled.

Add a BGP peer group by Name.

Enable the peer group.

Select the type of peer group as

IBGP

(Internal BGP, peering within an AS) or

EBGP

(External BGP—peering between two autonomous systems).

Select or create an AFI IPv4 profile to apply the settings in the profile to the peer group; default is

None

.

Select or create an AFI IPv6 profile to apply the settings in the profile to the peer group; default is

None

.

Apply all the elements of a Filtering Profile to the peer group.

Apply all the elements of a Filtering Profile to the peer group.

Select or create an authentication profile that is used to authenticate BGP peer communications; default is

None

.

Select or create a Timers profile to apply to the peer group; default is

None

.

Set the time-to-live (TTL) value in the IP header. Range is 1 to 255; a setting of 0 means use the default value: 1 for EBGP; 255 for IBGP.

Add a BGP peer by name, which must start with an alphanumeric character and contain a maximum of 31 characters, including letters, numbers, underscore, hyphen, period, and space.

Enable the BGP peer.

Enter the AS to which the peer belongs; range is 1 to 4,294,967,295.

Select or create an Authentication profile. Alternatively, select

inherit (Inherit from Peer-Group)

or

None

, both of which cause the peer to use the Auth profile specified for the peer group.

Select or create a Timers profile. Alternatively, select

inherit (Inherit from Peer-Group)

or

None

, both of which cause the peer to use the Timers profile specified for the peer group.

Select

inherit (Inherit from Peer-Group)

or

None

, both of which cause the peer to use the value specified for the peer group.

Select to cause the firewall to check the AS_PATH attribute of a route in its forwarding information base (FIB) before it sends the route in an Update, to ensure that the peer AS number is not on the AS_PATH list. If it is, the firewall removes it to prevent a loop. Default is enabled.

Inherit-vr-global-setting (Inherit Protocol’s Global BFD Profile)

Default is None (Disable BFD)

Select or create a Redistribution profile to specify which static or connected IPv4 routes to redistribute to the IPv4 unicast route table. Default is

None

.

Select or create a Redistribution profile to specify which static or connected IPv6 routes to redistribute to the IPv6 unicast route table. Default is

None

.

Select

IPv4

or

IPv6

.

Add a corresponding IPv4 or IPv6 network address; subnets with matching network addresses are advertised to BGP peers of the logical router.
