Watch what address you are sourcing the pings from. If you dont specify it will be the outgoing interface based on the routing table. R2 or another router in the path doesnt have a route back to the outgoing interface on R4 that the ping is leaving from.
Check your show ip routes in both directions for the IP addresses that your pings are sourced from Aaron On Sun, Jul 31, 2011 at 1:32 PM, Benjamin Long <[email protected]>wrote: > Hi, > > I just completed redistribution and I cannot ping from R4 to R1.
