Prerequisites for Implementing Routing Policy
The following are prerequisites for implementing Routing Policy on Cisco IOS XR Software:
•
You must be in a user group associated with a task group that includes the proper task IDs. The command
reference guides include the task IDs required for each command. If you suspect user group assignment
is preventing you from using a command, contact your AAA administrator for assistance.
•
Border Gateway Protocol (BGP), integrated Intermediate System-to-Intermediate System (IS-IS), or
Open Shortest Path First (OSPF) must be configured in your network.
Restrictions for Implementing Routing Policy
These restrictions apply when working with Routing Policy Language implementation on Cisco IOS XR
software:
•
An individual policy definition of up to 1000 statements are supported. The total number of statements
within a policy can be extended to 4000 statements using hierarchical policy constructs. However, this
limit is restricted with the use of apply statements.
•
When a policy that is attached directly or indirectly to an attach point needs to be modified, a single
commit operation cannot be performed when:
