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

Predefined user roles

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.
