rr-filter
Use rr-filter to create an RR reflection policy so that only IBGP routes whose extended community attribute
matches the specified extended community list are reflected.
Use undo rr-filter to restore the default.
Syntax
rr-filter extended-community-number
undo rr-filter
Default
An RR does not filter reflected routes.
Views
BGP VPNv4 address family view
Predefined user roles
network-admin
Parameters
extended-community-number: Specifies an extended community list by its number in the range of 1 to
199.
Usage guidelines
By configuring different RR reflection policies on RRs in a cluster, you can implement load balancing
among the RRs.
