Oddly enough even though r2 has a direct connection to 150.100.24.0 my debugs are showing that it is sending ping replies to r4 down to r5! If it has s direct connection shouldn't that beat the iBGP route from R5 (AD 200)? Any thoughts? BTW I did not add the ip route for 200.0.0.4 just yet, but the conept is that this whole lab allows a certain number of static routes and I thought I would try an alternate config for this question. Especially, since this question specifically tells you want interface to include from the different routers into the BGP process, I would never thought to do this solution with the NETWORK command (on a real exam). I guess in the exam i would ask the Proctor for advice on this matter. Look at he route output below: R2#sho ip route 150.100.24.4 Routing entry for 150.100.24.4/32 Known via "bgp 64512", distance 200, metric 0 Tag 64513, type internal Last update from 150.100.100.5 03:06:50 ago Routing Descriptor Blocks: * 150.100.100.5, from 150.100.100.5, 03:06:50 ago Route metric is 0, traffic share count is 1 AS Hops 0 Route tag 64513 R2#myip Interface IP-Address OK?
