Chapter 13 Configuring a VPN Using Easy VPN and an IPSec Tunnel

Configuration Tasks

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:

SUMMARY STEPS

1.interface type number

2.crypto map map-name

3.exit

DETAILED STEPS

	Command or Action	Purpose
Step 1
	interface type number	Enters the interface configuration mode for the
	Example:	interface to which you want the crypto map
		applied.
	Router(config)# interface fastethernet 4
	Router(config-if)#
Step 2
	crypto map map-name	Applies the crypto map to the interface.
	Example:	See Cisco IOS Security Command Reference for
		more details about this command.
	Router(config-if)# crypto map static-map
	Router(config-if)#
Step 3
	exit	Returns to global configuration mode.
	Example:
	Router(config-crypto-map)# exit
	Router(config)#

Create an Easy VPN Remote Configuration

The router acting as the IPSec remote router must create an Easy VPN remote configuration and assign it to the outgoing interface.

Perform these steps to create the remote configuration, beginning in global configuration mode:

SUMMARY STEPS

1.crypto ipsec client ezvpn name

2.group group-name key group-key

3.peer {ipaddress hostname}
