if ospf-area in ospf-area-set* then
set ospf-metric 200
elseif ospf-area in (10.0.0.1, 10.0.0.2) then
set ospf-metric 300
endif
end-policy
!
end
This completes the configuration of routing policy with wildcards for OSPF area sets.
VRF Import Policy Enhancement
The VRF RPL based import policy feature provides the ability to perform import operation based solely on
import route-policy, by matching on route-targets (RTs) and other criteria specified within the policy. No
need to explicitly configure import RTs under global VRF-address family configuration mode. If the import
RTs and import route-policy is already defined, then the routes will be imported from RTs configured under
import RT and then follows the route-policy attached at import route-policy.
Use the source rt import-policy command under VRF sub-mode of VPN address-family configuration mode
to enable this feature.
Flexible L3VPN Label Allocation Mode
The flexible L3VPN label allocation feature provides the ability to set label allocation mode using a route-policy,
where different allocation modes can be used for different sets of prefixes. Thus, label mode can be chosen
based on arbitrary match criteria such as prefix value and community.
Use the label mode command to set the MPLS/VPN label mode based on prefix value. The Label-Mode
attach point enables you to choose label mode based on any arbitrary criteria.
How to Implement Routing Policy
This section contains the following procedures:
Defining a Route Policy
This task explains how to define a route policy.
Note
•
If you want to modify an existing routing policy using the command-line interface (CLI), you must
redefine the policy by completing this task.
•
Modifying the RPL scale configuration may take a long time.
•
BGP may crash either due to large scale RPL configuration changes, or during consecutive RPL
changes. To avoid BGP crash, wait until there are no messages in the BGP In/Out queue before
committing further changes.
