Can anyone look at my configuration? I am unable to ping 1.1.1.1 from Router 5 in BGP 200. This has been bothering me any help would be greatly appreciated.
Here is my configuration .

I don't see where the 4.4.4..x network is in BGP. Is it being advertised to R1 from R2?

Hi,
Can you provide a "show ip route" from each router?
12-18-2016 04:54 PM
Here is the ip route from Router 5. I see route 1.1.1.0 in the routing table, but can't ping it. I can however ping from Router 4.
This is R4 Routing table
12-18-2016 05:00 PM
Here's the trace. It seems like it doesn't know where to go once it reaches R2

Hi,
Can you provide the full sh run output for R2, along with a sh ip route.

Ugghhh you're right......Shheess Why didn't I see that. The 4.4.4.X network was not advertised into BGP so it couldn't carry it to the next AS system.
Thank you very much!
