In reply to Ed Harmoush. If OSPF is on your list, Forwarding Address would be a great topic for discussion. Great Article on BGP.

In reply to Karol.

That is exactly what happened. When the link to R2 was shut down, the remaining paths through R3 and R4 were tied since they were both present in the BGP table when R1 lost the path through R2. R1 used Step 11 (lowest Router-ID) to break the tie to select R3 as the next best path.

Often people consider that R3 was selected because the R3 path was learned before R4, meaning it had an older absolute age. But Trial 2 proves that wasn’t the case. I elaborate on it further in the “What Happened” section.

Hi Ed! How does Trial 2 differ from Trial 1? When you shut down the 9.22.11.2 peer, both remaining paths were also present in the topology table, so following this logic – there should be a tie, with step 11 as a tie-breaker.
