Configuring A Bidirectional Mpls Te Tunnel - HP FlexNetwork HSR6600 Configuration Manual

•
If you configure the tunnel destination address as the primary IP address of an interface on the
egress node, you must enable MPLS TE, and configure OSPF or IS-IS on that interface. This
makes sure the primary IP address of the interface can be advertised to its peer.
•
The route to the tunnel interface address and the route to the tunnel destination must be in the
same OSPF area or at the same IS-IS level.
Configuring IGP shortcut
Step
1. Enter system view.
2. Enter MPLS TE tunnel
interface view.
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 in tunnel interface view:
Step
1. Enter system view.
2. Enter MPLS TE tunnel
interface view.
3. Enable forwarding adjacency.

Configuring a bidirectional MPLS TE tunnel

Restrictions and guidelines
To create a bidirectional MPLS TE tunnel, create an MPLS TE tunnel interface on both ends of the
tunnel and enable the bidirectional tunnel feature 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 CRLSP at the passive end.
•
For an associated bidirectional tunnel, specify a reverse CRLSP at both ends of the tunnel.
Prerequisites
Before you create a bidirectional MPLS TE tunnel, perform the following tasks:
•
Disable the PHP feature 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.

Remarks
N/A
N/A
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.
