Hello all,
Having trouble with a route to one of my branch networks over my WAN. Traceroute is just bouncing around on our 4500 even though there is a static route configured on it. Any idea why?
#traceroute 10.210.1.122
Type escape sequence to abort.
Tracing the route to 10.210.1.122

Hello,
post the configurations of both routers (that is, both ends of the traceroute)...

Hi
As Georg mentioned please share the configuration from both devices. Usually when there is a loop the packet hops between 2.
Is this AS 7018 on your side or ISP side?

Its our 4500
The trace is ran from one of our branch routers to another branch. The loop is at our main site which is a hop between the two branches. Which config do you need? The trace source and 4500 where the trace is looping?
