9.12.2 BGP instance and view

BGP instance is a normal BGP process. The result of route selection goes to the kernel routing table. You can setup different AS at the same time when BGP multiple instance feature is enabled.

Command: router bgp as-number {}
Make a new BGP instance. You can use arbitrary word for the name.

 
bgp multiple-instance
!
router bgp 1
 neighbor 10.0.0.1 remote-as 2
 neighbor 10.0.0.2 remote-as 3
!
router bgp 2
 neighbor 10.0.0.3 remote-as 4
 neighbor 10.0.0.4 remote-as 5

BGP view is almost same as normal BGP process. The result of route selection does not go to the kernel routing table. BGP view is only for exchanging BGP routing information.

Command: router bgp as-number view name {}
Make a new BGP view. You can use arbitrary word for the name. This view's route selection result does not go to the kernel routing table.

With this command, you can setup Route Server like below.

 
bgp multiple-instance
!
router bgp 1 view 1
 neighbor 10.0.0.1 remote-as 2
 neighbor 10.0.0.2 remote-as 3
!
router bgp 2 view 2
 neighbor 10.0.0.3 remote-as 4
 neighbor 10.0.0.4 remote-as 5
