Smart peeps,
Like many others on GS I have gotten in the habit of using "debug ip routing"
through most of the lab. I like that I get instant feedback if I accidently
kill a route or two, and enjoy seeing them pop in when adding a network
statement or redistribution. That being said I have noticed something in
many labs related to OSPF load balancing and just want to be sure I'm not
habitually screwing something up.
When I have two paths to the same destination and am equal cost load
balancing to that destination, I've noticed that any time I have traffic
running (ping for example) across the load balanced link (with debug ip
routing enabled) I see a message noting an RDB change from Path A to Path B.
If I ping again it swaps from B to A.
When I do a show ip route 1.2.3.4 I see that I'm load balancing on 2 paths
with a traffic share count of 1 on each path, which makes sense.
I guess I just want to be sure this output is normal and that I haven't
missed anything. It's especially abnoxious when a BGP peering session is
running acros the load balanced path. The TCP session results in a steady
stream of these messages.
Thanks in advance,
wnaB
