Configuring A Bidirectional Mpls Te Tunnel - HP 6127xlg Configuration Manual

Step
3. Enable IGP shortcut.
4. Assign a metric to the
MPLS TE tunnel.
Configuring forwarding adjacency
To use forwarding adjacency, you must establish two MPLS TE tunnels in opposite directions between two
nodes, and configure forwarding adjacency on both the nodes.
To configure forwarding adjacency:
Step
1. Enter system view.
2. Enter MPLS TE tunnel interface
view.
3. Enable forwarding
adjacency.

Configuring a bidirectional MPLS TE tunnel

Before you create a bidirectional MPLS TE tunnel, complete the following tasks:
Disable the PHP function on both ends of the tunnel.
•
To set up a bidirectional MPLS TE tunnel in co-routed mode, you must specify the signaling protocol
•
as RSVP-TE, and use the mpls te resv-style command to configure the resources reservation style as
FF for the tunnel.
To set up a bidirectional MPLS TE tunnel in associated mode and use RSVP-TE to set up one CRLSP
•
of the tunnel, you must use the mpls te resv-style command to configure the resources reservation
style as FF for the CR-LSP.
To create a bidirectional MPLS TE tunnel, create an MPLS TE tunnel interface on both ends of the tunnel
and enable the bidirectional tunnel function on the tunnel interfaces:
For a co-routed bidirectional tunnel, configure one end of the tunnel as the active end and the other
•
end as the passive end, and specify the reverse CR-LSP at the passive end.
For an associated bidirectional tunnel, specify a reverse CR-LSP at both ends of the tunnel.
•
To configure the active end of a co-routed bidirectional MPLS TE tunnel:
Step
1. Enter system view.
Command
mpls te igp shortcut [ isis | ospf ]
mpls te igp metric { absolute value |
relative value }
Command
system-view
interface tunnel tunnel-number
[ mode mpls-te ]
mpls te igp advertise [ hold-time
value ]
Command
system-view

Remarks
By default, IGP shortcut is
disabled.
If no IGP is specified, both
OSPF and IS-IS will include the
MPLS TE tunnel in route
calculation.
By default, the metric of an
MPLS TE tunnel equals its IGP
metric.
