Hi,

I am missing some routes in BGP [sho ip bgp].

The network is:

R9 [65109] <--> R3 [65109] <--> R7 [65109]
^ ^ ^
| | |
v v v
R5 [65110] <--> R2 [65110] <--> R6 [65110]

R9 has 2 loopbacks: 10.108.99.99/24 and 10.108.199.199/24
R3 has 2 loopbacks: 10.108.33.33/24 and 10.108.133.133/24
and so on..

All the routers peers through 99.99, 33.33 and so on..
Here is the config for R3

router bgp 65109
 bgp router-id 33.33.33.33
 bgp cluster-id 174884229
 bgp log-neighbor-changes
 network 10.108.133.0 mask 255.255.255.0
 neighbor ibgp peer-group
 neighbor ibgp update-source Loopback0
 neighbor ebgp peer-group
 neighbor ebgp ebgp-multihop 2
 neighbor ebgp update-source Loopback0
 neighbor 10.108.22.22 remote-as 65110
 neighbor 10.108.22.22 peer-group ebgp
 neighbor 10.108.77.77 remote-as 65109
 neighbor 10.108.77.77 peer-group ibgp
 neighbor 10.108.99.99 remote-as 65109
 neighbor 10.108.99.99 peer-group ibgp
!
All the other ones are similar

----------------------------------------
When doing a show ip bgp on R9, I am missing the network from R7

BGP table version is 3, local router ID is 99.99.99.99
