rr-filter (BGP-VPNv6 subaddress family view)
Use rr-filter to create an RR reflection policy so that only iBGP routes whose Extended Communities
attribute matches the specified one 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 the reflected routes.
Views
BGP-VPNv6 subaddress family view
Default command level
2: System level
Parameters
extended-community-number: Specifies the number of the Extended Communities attribute supported by
the RR, in the range of 1 to 199.
Usage guidelines
By configuring different RR reflection policies on different RRs, you can implement load balancing among
the RRs.
