Flushing OSPF routers tables in the entire network.

[jimmycher]

We have a small network of 100 devices, running OSFPv2.  On occasion, I'll have a "guest" router added to the network, at which time, I want to delete all routers routing-tables, and rebuild from scratch.  I don't want the guest having the ability to see older routes, or interrogate others.

This might be overkill, but it is what the customer wants.

Any thoughts?

Interesting situation. Can I suggest:

1- Peer on your regular network using MD5 authentication so the guest cannot establish a peer without your knowledge.

2- Designate the guest router to peer in its own area, make it totally stubby and only send the default route to it.

3- You could also MD5 authenticate with the peer with a unique password / key.

Hope this helps
