We have an Adtran that has some routes I don't know what they are for. I want to rip them out but need to make sure they aren't being used. I've done some looking around and don't see anything.
In short I'd like to see traffic statistics in relation to routes. IE X route has passed X packets or has X connections.
"show IP policy-session" while looking at the destination IP of the route might be of some value if the routes are in use at the time.
Otherwise there really isn't a metric showing how often a route has been used. Look at the destination subnets and next hop and see if the routes make sense.
