Chapter 64 Configuring Routing Policies
OSPF Interface Policy Page
Whenever you configure an interface with a new key, the router sends multiple copies of the same packet,
each authenticated by different keys. The router stops sending duplicate packets when it detects that all
of its neighbors have adopted the new key.
Note You should use authentication with all routing protocols when possible, because attackers can use route
redistribution between OSPF and other protocols (such as RIP) to subvert routing information.
