We have several routers running OSPF in area 0. These routers are redistributing static routes pointing to remote networks belonging of each of them. Ok all routers know remote networks of other routers by OSPF.
We have been testing and if you shutdown an interface (there are routes with remote ip address as next-hop), OSPF routers remains with this route in its routing table.
Why this routes remains in OSPF routers routing table if its router interface is down? What I´m doing wrong? Here´s OSPF configuration in one OSPF router:
Your static routes are pointing to an IP address. If after shutting the interface, the router still has a route to the destination IP (perhaps there's a more general route somewhere) then the static route is still valid. Try making your routes point to the interface. Example: ip route 188.8.131.52 255.255.255.0 ser 0. This way when the interface is down, the route will no longer be valid.
Question We run asr9001 with XR 6.1.3, and we have a very long delay to

investigation, the there is 1s delay between the client KEXDH_INIT and

Introduction The purpose of this document is to demonstrate the Open

present in a non-backbone area. The V-bit is signaled in Type-1 LSA only
if the router is the endpoint of one or ...
