Chapter 18 Configuring Ethernet over MPLS
Configuring MPLS-TE
Ethernet FCS preservation is off by default on the ML-Series card. Configure Ethernet FCS preservation
at the interface or sub-interface configuration level with the [no] fcs-preservation-on command. To
operate correctly, both ends of the EoMPLS tunnel need to be configured for FCS preservation.
Configuring MPLS-TE
Perform the following tasks on the MPLS network before you enable MPLS-TE on the ML-Series card:
• Turn on MPLS tunnels
• Turn on OSPF
To configure MPLS-TE on the ML-Series card, perform the tasks described in the following sections:
• Configuring an ML-Series Card for Tunnels Support
• Configuring an Interface to Support RSVP-Based Tunnel Signalling and IGP Flooding
• Configuring OSPF and Refresh Reduction for MPLS-TE
• Configuring an MPLS-TE Tunnel
Note The ML-Series card does not support MPLS-TE with IS-IS.
Note Cisco Express Forwarding (CEF) is on by default on the ML-Series card.
Configuring an ML-Series Card for Tunnels Support
To configure an ML-Series card to support tunnels, use the following commands in global configuration
mode:
Configuring an Interface to Support RSVP-Based Tunnel Signalling and IGP
Flooding
To configure an interface to support RSVP-based tunnel signalling and IGP flooding, use the following
commands in interface configuration mode:
Note You must enable the tunnel feature on interfaces or sub-interfaces that you want to support
MPLS-TE.
Command Purpose
Step 1 Router(config)# mpls traffic-eng tunnels Enables the MPLS-TE tunnel feature on a device.
