Configuring a tunnel interface
Configure a Layer 3 virtual tunnel interface on each device on a tunnel so that devices at both ends can
send, identify, and process packets from the tunnel.
The switch cannot directly route a tunneled packet based on the packet's destination address. The packet
is sent to a tunnel-type service loopback group, which then delivers the packet to the forwarding module
for Layer 3 forwarding. Therefore, you must configure a tunnel-type service loopback group. Otherwise,
the tunnel interface will fail to forward and receive packets. For information about service loopback
group, see Layer 2—LAN Switching Configuration Guide.
To configure a tunnel interface:
