The Nokia 7750 SR allows the setting of the maximum number of routes that can be accepted in a VRF for a VPRN service.

The "maximum-routes" command is used to specify the maximum number of remote routes that can be held within a VRF for a VPRN service.

When the "maximum-routes" command is used with the "log-only" parameter, new routes are still learned.

Once the "threshold" value is reached, no new routes are added to the VRF.
