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 the if-match rd-filter 1 command is configured, but the rd-filter 1 command is not configured, all routes will be permitted.
If the if-match rd-filter 1 and ip rd-filter 1 permit 1:1 commands are configured, routes with RD 1:1 will be permitted.

Configuration Impact

Routes are filtered based on RD attributes. The routes with the specified RD attributes are permitted and those without the specified RD attributes are denied.

Example

# Define a filtering rule in the tunnel-selector view to match an RD filter.

<HUAWEI> system-view
[~HUAWEI] ip rd-filter 1 permit 100:1
[*HUAWEI] tunnel-selector tps permit node 10
[*HUAWEI-tunnel-selector] if-match rd-filter 1
