no-control-word: Disables the control word option.

Use the mpls static-l2vc destination command to create a static VC between 
CEs connected to different PEs.

Use the undo mpls static-l2vc command to delete the static VC.

■

You must configure the command on both PEs. The destination address is the 
IP address of the peer PE. The outgoing label and incoming label are 
respectively the incoming label and outgoing label of the peer.

■

If you do not specify the tunneling policy, or specify the tunneling policy name 
but do not configure the policy, the default policy is used. The default 
tunneling policy uses LSP tunnels and the load balance number is one.

■

Currently, only L2VPNs using ATM, PPP, FR, or HDLC encapsulation support the 
control word option.

mtu-value: MTU for the L2VPN. It ranges from 128 to 1,500 and defaults to 1,500.

Use the mtu command to set the maximum transmission unit (MTU) for the 
kompella connections.

Use the undo mtu command to restore the default.
