Command Remarks
3. Define an ACL rule.
rule [ rule-id ] { deny | permit } protocol
[ destination { dest-addr dest-wildcard | any } |
destination-port operator port1 [ port2 ] | dscp
dscp | established | fragment | icmp-type
{ icmp-type icmp-code | icmp-message } |
logging | precedence precedence | reflective |
source { sour-addr sour-wildcard | any } |
source-port operator port1 [ port2 ] | time-range
time-name | tos tos | vpn-instance
vpn-instance-name ] *
N/A
4. Return to system view.
quit N/A
5. Create a policy node and
enter policy-based-route
view.
policy-based-route policy-name { permit | deny }
node node-number
You can create
multiple policy nodes
in one policy.
6. Reference the ACL that
target traffic should match.
if-match acl acl-number N/A
7. Specify the output interface
to be the tunnel interface.
apply output-interface tunnel number1 [ tunnel
number2 ]
N/A
8. Return to system view.
quit N/A
9. Enable policy based
routing.
• Enable local policy based routing:
ip local policy-based-route policy-name
• Enable policy based routing for an interface:
a. interface interface-type interface-number
b. ip policy-based-route policy-name
Use one of the
methods.
For more information about configuring policy routing, see ACL and QoS Command Reference and the
Layer 3—IP Routing Command Reference.
Forwarding traffic along MPLS TE tunnels through automatic
route advertisement
Two methods, 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 methods. If it is absolute, the metric is directly used for path calculation. If it is relative, the cost of
the corresponding IGP path must be added to the metric before it can be used 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.
