am getting a RIP failure when i used BGP backdoor. do i need to do some extra steps to rectify that. or its normail the setup is like as below
R1(AS1)--FR--R2(AS2)--FR---R3(AS3)
1. Running ospf in between all three routers.
2. I have loopback address 3.3.15.0/24 on R3 which is part of OSPF and all three router learning about it via OSPF.
3 Then i introduced in BGP in AS3 on R3
"network 3.3.15.0 mask 255.255.255.0"
4. it appeard on R2 with BGP AD 20
5. On R2 under BGP i used
"network 3.3.15.0 mask /24 backdoor command.
6 I start learning via OSPF w/ AD 110 on R2 instead og eBGP AD 20
7. Now on R1 under "sh ip BGP" it apear as
r> 3.3.15.0/24 3.3.2.2
can we leave this as it is or is there any fix required toretify that
specific configs are below:
R3:
interface Loopback11
ip address 3.3.15.1 255.255.255.0
router bgp 3
network 3.3.15.0 mask 255.255.255.0
router ospf 1
network 3.3.15.0 0.0.0.255 area 10
R2:
router bgp 2
network 3.3.15.0 mask 255.255.255.0 backdoor
R3:
show ip bgp
r> 3.3.15.0/24 3.3.6.6
