(Optional.) Configuring MPLS TE FRR
Only MPLS TE tunnels established by RSVP-TE support this configuration.
Enabling MPLS TE
Enable MPLS TE on each node and interface that the MPLS TE tunnel traverses.
Before you enable MPLS TE, complete the following tasks:
• Configure static routing or IGP to make sure all LSRs can reach each other.
• Enable MPLS. For information about enabling MPLS, see "Configuring basic MPLS."
To enable MPLS TE:
1. Enter system view.
system-view
N/A
2.
MPLS TE view.
mpls te
disabled.
3. Return to system view.

4. Enter interface view.

5. Enable MPLS TE

disabled on an interface.
Configuring a tunnel interface
To configure an MPLS TE tunnel, you must create an MPLS TE tunnel interface and enter tunnel
interface view. All MPLS TE tunnel attributes are configured in tunnel interface view. For more
information about tunnel interfaces, see Layer 3—IP Services Configuration Guide.
Perform this task on the ingress node of the MPLS TE tunnel.
To configure a tunnel interface:
1. Enter system view.
system-view
N/A
2. Create an MPLS TE tunnel
interface and enter tunnel
interface view.
interface tunnel
tunnel-number
mode
mpls-te
By default, no tunnel interface is
created.
3. Configure an IP address for
the tunnel interface.
ip address
ip-address
{ mask-length | mask }
By default, a tunnel interface does
not have an IP address.
4.
destination address.
destination
ip-address
By default, no tunnel destination
address is specified.
Configuring DS-TE
DS-TE is configurable on any node that an MPLS TE tunnel traverses.
