IBGP to EBGP unable to ping

[ubsaccount]

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 .

Hi,

Can you provide a "show ip route" from each router?

[ubsaccount]

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 

[ubsaccount]

Here's the trace.  It seems like it doesn't know where to go once it reaches R2

[mattjones03]

Hi,

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

[ubsaccount]

Problem was solved with Chris

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

[ubsaccount]

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!
