Routing – how to remove the OLD_Router-ID from ospf toplolgy table


After explicitly assigning a Router-ID to the ospf process the "old RouterID" remains in the topology table of the whole ospf area.

How can I remove the old router ID?
What is the max age for it? (3600??)
Wont this entry cause any problems?

You need to use the clear ip ospf process command after you change a router ID. Alternatively, you could just restart the router, but that seems extreme.
