Applying the crypto map to the physical interface instructs the router to evaluate all the traffic against
the security associations database. With the default configurations, the router provides secure
connectivity by encrypting the traffic sent between remote sites. However, the public interface still
allows the rest of the traffic to pass and provides connectivity to the Internet.
Perform these steps to apply a crypto map to an interface, beginning in global configuration mode:
Step 3

exit
Example:
Router(config-crypto-map)# exit
Router(config)#
Returns to global configuration mode.
Step 5
crypto map map-name seq-num [ipsec-isakmp]
