![]() ![]() If the route has a nexthop marked as invalid, most likely this is due to it can'tīe resolved from the current RIB, but only via default route.įor instance, Cisco allows this by default (can't find even a knob to turn itįor eBGP sessions it might be also combined with `disable-ebgp-connected-route-check`. Would do the trick, but it's a workaround. Adding a static /32, /128 route for the peer Is not accessible from the RIB, but only via default route.
