Usage Guidelines

Usage Scenario

To filter the routes to be received by MBGP, run the route-filter import command. MBGP adds only the received routes that match the route-filter to the MBGP routing table.

To filter the routes to be advertised using a route-filter, run the route-filter export command.

If you specify a route protocol in the command, MBGP filters only the routes of this protocol before advertising them.
If you do not specify any protocol in the command, MBGP filters all routes before advertising them.

Example

# Use the route-filter named aaa to filter the routes to be advertised by MBGP.

<HUAWEI> system-view
[~HUAWEI] bgp 100
[*HUAWEI-bgp] ipv4-family multicast
[*HUAWEI-bgp-af-multicast] route-filter aaa export

# Use the route-filter named aaa to filter the routes to be received by MBGP.

<HUAWEI> system-view
[~HUAWEI] bgp 100
[*HUAWEI-bgp] ipv4-family multicast
[*HUAWEI-bgp-af-multicast] route-filter aaa import
