Configuring an extended community list

You can configure multiple items for an extended community list that is identified by number. The
relationship between items is logic OR. A route that matches one item matches the extended
community list.
To configure an extended community list:

Configuring a routing policy

Configuration prerequisites

Configure filters and routing protocols, and determine the routing policy name, node numbers, match
criteria, and the attributes to be modified.

Creating a routing policy

Follow these guidelines when you create a routing policy:
•
The routing information matching all the if-match clauses of a permit-mode node is handled by
the apply clauses of the node, without needing to match against the next node. The routing
information that does not match the node goes to the next node for a match.
•
The apply clauses of a deny-mode node are never executed. The routing information matching
all the if-match clauses of the node cannot pass the node, or go to the next node. The route
information that does not match node goes to the next node for a match.
•
For a routing policy that has more than one node, configure at least one permit-mode node. A
route that does not match any node cannot pass the routing policy. If all the nodes are in deny
mode, no routing information can pass the routing policy.
To create a routing policy:

Create a routing policy and a node and

Configuring if-match clauses

Follow these guidelines when you configure if-match clauses:
•
The if-match clauses of a routing policy node have a logical AND relationship. A route must
match all if-match clauses before it can be handled by the apply clauses of the node. If an
if-match command exceeds the maximum length, multiple identical if-match clauses are
