Hi


Stuck in active means the router/L3 switch is actively qureying neighbors for a route to 10.0.0.0/8 but is not getting replies from all neighbors.


Check for congested links which would delay the responses or a router under a very high CPU load which again coudl delay a response.


Also have a look at this link

Hi


Okay, it would be a good idea to read the attached link. From your output above


via 10.11.1.2 (Infinity/Infinity), r, Vlan11, serno 5549635


The same , r, means USL3ATL002 is still waiting on a reply from 10.11.1.2.


So you need to look at 10.11.1.2.

Why is it only this one route that the switches are complaining about?


Is this static route 10.0.0.0 with a metric 200 messing up the routing?
