Usage Guidelines

Usage Scenario

The if-match rd-filter command and the ip rd-filter command work together to filter routes based on RD attributes. For example:

If if-match rd-filter 1 is configured, but rd-filter 1 is not configured, then all current routes will be permitted.
If if-match rd-filter 1 is configured, and ip rd-filter 1 permit 1:1 has been configured, then routes with RD 1:1 will be permitted.

Prerequisites

The if-match rd-filter command must be run after the route-policy command is run.

Precautions

The routing policy matches routes using the RD filter. Routes that match the RD filter will be checked by other if-match clauses of this node. Routes that do not match the RD filter will be checked by the next node.

Example

# Define a matching rule to match an RD filter.

<HUAWEI> system-view
[HUAWEI] route-policy abc permit node 10
[HUAWEI-route-policy] if-match rd-filter 1
