A router interface can be associated with only one IPSec policy. However, an
IPSec policy can be associated with multiple router interfaces, and a crypto map
can specify more than one peer for a connection. The following diagram shows
two router interfaces associated with a policy, and a crypto map specifying two
peers.
There are six VPN connections in this configuration, as both Dialer 3 and
Serial 1/1 have connections to Seattle, Chicago, Topeka, and Lawrence. Cisco
SDM would show the links to Topeka and Lawrence as one connection for both
interfaces.
