Forwarding Traffic Along Mpls Te Tunnels Through Automatic Route Advertisement - HP 10500 SERIES Configuration Manual

Step
2. Create a static route for
forwarding traffic along an
MPLS TE tunnel.
Forwarding traffic along MPLS TE tunnels through automatic
route advertisement
Two approaches, IGP shortcut and forwarding adjacency, are available to automatically advertise MPLS
TE tunnel interface routes to IGPs, allowing traffic to be routed down MPLS TE tunnels.
You can assign a metric, either absolute or relative, to TE tunnels for the purpose of path calculation in
either approach. If it is absolute, the switch directly uses the metric for path calculation. If it is relative, the
switch adds the cost of the corresponding IGP path to the metric before using it for path calculation.
Enable OSPF or IS-IS on the tunnel interface of the MPLS TE tunnel before configuring automatic route
advertisement.
To use automatic route advertisement, specify the destination address of the TE tunnel as the LSR ID of the
peer and advertise the tunnel interface address to IGPs, such as OSPF and ISIS.
Configure an IGP shortcut:
1.
Step
1. Enter system view.
2. Enter MPLS TE tunnel interface
view.
3. Configure the IGP to take the
MPLS TE tunnels in up state
into account when performing
enhanced SPF calculation.
4. Assign a metric to the MPLS TE
tunnel.
5. Submit
configuration.
6. Exit to system view.
7. Enter OSPF view.
8. Enable
function.
Configure a forwarding adjacency:

Remarks
The interface-type argument in the
ip route-static command must be
tunnel. In addition, the preference
value must be set.

routing, see Layer 3—IP Routing
Configuration Guide.
Remarks

N/A
MPLS TE tunnels are not considered
in the enhanced SPF calculation of
IGP.
If no IGP type is specified, the
configuration applies to both OSPF
and ISIS by default.
Optional.
The metrics of TE tunnels equal the
metrics of their corresponding IGP
routes by default.
