Configure a BGP Peer with MP-BGP for IPv4 or IPv6 Unicast

Enable MP-BGP Extensions for a peer.
Configure the following so that a BGP peer can carry IPv4 or IPv6 unicast routes in Updates packets and the firewall can use IPv4 or IPv6 addresses to communicate with its peer.
Select
Network
Virtual Routers
and select the virtual router you are configuring.
Select
BGP
.
Select
Peer Group
and select a peer group.
Select a BGP peer (router).
Select
Addressing
.
Select
Enable MP-BGP Extensions
for the peer.
For
Address Family Type
, select
IPv4
or
IPv6
. For example, select IPv6.
For
Subsequent Address Family
,
Unicast
is selected. If you chose
IPv4
for the Address Family, you can select
Multicast
also.
For
Local Address
, select an
Interface
and optionally select an
IP
address, for example, 2001:DB8:55::/32
For
Peer Address
, enter the peer’s
IP
address, using the same address family (IPv4 or IPv6) as the Local Address, for example, 2001:DB8:58::/32.
Select
Advanced
.
(
Optional
)
Enable Sender Side Loop Detection
. When you enable Sender Side Loop Detection, the firewall will check the AS_PATH attribute of a route in the BGP RIB before it sends the route in an update, to ensure that the peer AS number isn't in the AS_PATH list. The firewall doesn't advertise the route if the peer AS number is in the AS_PATH list. Usually the receiver detects loops, but this optimization feature has the sender perform the loop detection. Disable this feature to have the receiver perform loop detection.
Click
OK
.
(
Optional
) Create a static route and install it in the unicast route table because you want the route to be used only for unicast purposes.
