Configuring Pbr To Direct Traffic To An Mpls Te Tunnel Or Tunnel Bundle; Configuring Automatic Route Advertisement To Direct Traffic To An Mpls Te Tunnel Or Tunnel Bundle - HP HPE FlexNetwork MSR Router Series Configuration Manual

Configuring PBR to direct traffic to an MPLS TE tunnel or
tunnel bundle
For more information about the commands in this task, see Layer 3—IP Routing Command
Reference.
To configure PBR to direct traffic to an MPLS TE tunnel or tunnel bundle:
Step
1. Enter system view.
2. Create a PBR policy node
and enter policy node view.
3. Configure an ACL match
criterion.
4. Specify a tunnel interface or
a tunnel bundle interface as
the packet output interface.
5. Return to system view.
6. Apply the PBR policy.
Configuring automatic route advertisement to direct traffic to
an MPLS TE tunnel or tunnel bundle
You can use either IGP shortcut or forwarding adjacency to implement automatic route
advertisement. When you use IGP shortcut, you can specify a metric for the TE tunnel or the tunnel
bundle. If you assign an absolute metric, the metric is directly used as the MPLS TE tunnel's or
tunnel bundle's metric. If you assign a relative metric, the MPLS TE tunnel or tunnel bundle's metric
is the assigned metric plus the IGP link metric.
Before configuring automatic route advertisement, perform the following tasks:
•
Enable OSPF or IS-IS on the tunnel interface or tunnel bundle interface to advertise the tunnel
interface address (or the tunnel bundle interface address) to OSPF or IS-IS.
•
Enable MPLS TE for an OSPF area or an IS-IS process by executing the mpls te enable
command in OSPF area view or IS-IS view.
Follow these restrictions and guidelines when you configure automatic route advertisement:
•
The destination address of the MPLS TE tunnel or tunnel bundle can be the LSR ID of the
egress node or the primary IP address of an interface on the egress node. As a best practice,
configure the destination address of the MPLS TE tunnel or tunnel bundle as the LSR ID of the
egress node.
•
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.
