Configuring a tunnel interface
Configuration prerequisites
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.
Configuration guidelines
The tunnel bandwidth command sets a bandwidth value for dynamical routing protocols to calculate the
cost of the tunnel and does not affect the actual interface bandwidth. You can determine the value
according to the bandwidth of the actual output interface.
Configuration procedure
To configure a tunnel interface:
