Tunnel Termination Flow

Tunnel termination can be configured for received L2 or L3 packets.

You can configure settings to apply tunnel termination to received packets, either tunneled (both L2 and L3) or non-tunneled. Tunnel termination is performed at either ingress or egress depending on the policy configuration.

L2 tunnel termination flow is as follows:

1. The outer tunnel of L2 tunneled packets is removed.
2. The current position is shifted to the start of the inner L2 header.

L3 tunnel termination flow is as follows:

1. The L2 header is retrieved from the L2 outer header because L3 tunneled-packet inner headers do not have the L2 header.
2. The L3 outer header is stripped.
