Configuring an IPsec tunnel interface
An IPsec tunnel interface uses IPsec as the encapsulation protocol.
To configure an IPsec tunnel interface, complete the following tasks:
1. Create a tunnel interface and set the tunnel mode to IPsec over IPv4.
2. Specify the source address or source interface of the IPsec tunnel interface, which will be used as
the local address in IKE negotiation.
3. Configure the destination addresses of the tunnel interface for the local peer to initiate an IKE
negotiation. If you want the local peer to act only as an IKE negotiation responder, omit this
configuration.
4. Apply an IPsec profile to the IPsec tunnel interface.
After the link layer of the IPsec tunnel interface comes up, packets routed to the tunnel interface will be
protected by IPsec. To ensure that the link layer of the IPsec tunnel interface comes up, make sure the
following requirements are met:
• The source address of the tunnel interface is the IP address of the local physical interface that
connects to the remote.
• The IPsec tunnel interfaces of the IPsec tunnel are configured with proper IPsec profiles.
• The expected IKE SA and IPsec SAs are established between the local security gateway and the
peer gateway. Use the display ike sa command to view the status the IKE SA and the IPsec SAs.
Follow these steps to configure an IPsec tunnel interface:
