rr-filter (BGP VPNv4 address family view)

Use rr-filter to create a route reflector (RR) reflection policy.

Use undo rr-filter to restore the default.

Syntax

rr-filter ext-comm-list-number

undo rr-filter

Default

An RR does not filter reflected routes.

Views

BGP VPNv4 address family view

Predefined user roles

network-admin

Parameters

ext-comm-list-number: Specifies an extended community list number in the range of 1 to 199.

Usage guidelines

After this command is executed, only the VPNv4 routes that are permitted by the specified extended community list are reflected.

By configuring different RR reflection policies on RRs in a cluster, you can implement load balancing among the RRs.

For more information about extended community lists, see Layer 3—IP Routing Configuration Guide.

Examples

# Configure the RR to reflect only VPNv4 routes that are permitted by extended community list 10.
