Group,
Can someone help me fix this Confed BGP issue. I think i have done it right but somehow the BGP neighbour relationship between R9 and R4 is not being formed.Everything else works.All spokes and hub are in same subnet 153.1.200.x (where x is R#). Is there a gotcha i am missing ?
Here is the setup:
As 4000
*************************************************************
As 2000 AS 2001
R9---------------------| |-------------- R4(spoke)
(spoke) | |
| |
******************* |---------|********************************
| |
############# | |#########################
| |
R5---------------------| |--------------------R10(spoke)
(Hub) As 1000 As 1001
#############################################
As 400
The setup in words:R9 in As 20001, R4 in As 2001, R5 in 1000 and R10 in 1001. R9/R4 are in AS 4000 and R5/R10 is in AS 400.
The configs for routers are as follows:
R5 (Hub)
router bgp 1000
bgp router-id 153.1.1.5
bgp log-neighbor-changes
bgp confederation identifier 400
bgp confederation peers 1001
network 153.1.1.0 mask 255.255.255.0
neighbor 153.1.200.9 remote-as 4000
neighbor 153.1.200.9 send-community
neighbor 153.1.200.10 remote-as 1001
neighbor 153.1.200.10 next-hop-self
neighbor 153.1.200.10 send-community
neighbor 186.1.1.100 remote-as 100
neighbor 186.1.1.100 route-map com in
R4: (problem spoke)
router bgp 2001
no synchronization
bgp router-id 153.1.33.11 <-----(loopback0)
bgp log-neighbor-changes
bgp confederation identifier 4000
bgp confederation peers 2000
network 153.1.33.0 mask 255.255.255.0
neighbor 153.1.200.9 remote-as 2000
R9 (spoke)
router bgp 2000
no synchronization
bgp router-id 153.1.9.9
bgp log-neighbor-changes
bgp confederation identifier 4000
bgp confederation peers 2001
network 153.1.9.0 mask 255.255.255.0
neighbor 153.1.200.4 remote-as 2001
neighbor 153.1.200.5 remote-as 400
neighbor 153.1.200.5 route-map comm in
R10(spoke)
router bgp 1001
no synchronization
bgp router-id 153.1.4.4
bgp log-neighbor-changes
bgp confederation identifier 400
bgp confederation peers 1000
network 153.1.4.0 mask 255.255.255.0
neighbor 153.1.200.5 remote-as 1000
The Ping from R9 to R4 and vice-versa works.
R4#ping
Protocol [ip]:
Target IP address: 153.1.200.9
Repeat count [5]: 10
Extended commands [n]: y
Source address or interface: 153.1.200.4
Sending 10, 100-byte ICMP Echos to 153.1.200.9, timeout is 2 seconds:
!!!!!!!!!!
Success rate is 100 percent (10/10), round-trip min/avg/max = 116/126/212 ms
What am i misssing ? Thanks for ur time and answers in advance.
Thanks,
Annu
