BGP LAB issues

[Manoj Reddy]

Dear Team,

R4 is having the 2 loopback IPs and have configured BGP, and from R1

sh ip bgp

output I can see the R1 is learning the prefixes and below is the output of it:

But now when i am trying to ping it's not working from R1:

From R2 and R3 i am able to ping it succesfully, only from R1 it's not working.

Please let me know if i am missing any config

Hi @Manoj Reddy ,

R4 doesn't have a route back to R1 because R1 doesn't advertise any prefix to R4. You need to add a network statement on R1 to advertise the loopback interface or any of the other connected prefixes. 

the reason it works from R2 and R3 is that they are directly connected to R4.

@Harold Ritter, Thanks it works now and I am able to reach R4 from R1.
