Apply the Crypto Map to the Physical Interface
Apply the Crypto Map to the Physical Interface
The crypto maps must be applied to each interface through which IP Security (IPsec) traffic flows.
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
reverse-route
Example:
Router(config-crypto-map)#
reverse-route
Router(config-crypto-map)#
Creates source proxy information for the crypto
map entry.
See the
Cisco IOS Security Command Reference
for details.
Step 4

Example:
Router(config-crypto-map)#
