Usage Guidelines

Usage Scenario

After a route-filter is created, you can run the peer route-filter export command to use the route-filter to filter the routes to be advertised to a specified BGP peer. The command configuration ensures that only desired routes are advertised, which helps manage routes and reduces the routing table size and system resource consumption.

Prerequisites

The route-filter paragraph editing interface view has been displayed and a route-filter has been created using the edit xpl route-filter command.

Precautions

The peer route-filter command is mutually exclusive with the peer as-path-filter, peer filter-policy, peer ip-prefix, peer route-policy commands.

If a peer is specified when the peer route-filter command is run, a peer group is specified when the peer capability-advertise orf command is run, and then the peer is added to the peer group, the peer cannot inherit the configuration of the peer capability-advertise orf command from the peer group.

Example

# Apply the route-filter named aaa to the routes to be advertised to a specified BGP peer group.

<HUAWEI> system-view
[~HUAWEI] xpl route-filter aaa
[~HUAWEI-xpl-filter] end-filter
[*HUAWEI] bgp 100
[*HUAWEI-bgp] peer 10.1.1.1 as-number 100
[*HUAWEI-bgp] ipv4-family sr-policy
[*HUAWEI-bgp-af-ipv4-srpolicy] peer 10.1.1.1 enable
[*HUAWEI-bgp-af-ipv4-srpolicy] peer 10.1.1.1 route-filter aaa export
