Parameters
extended-community-list-number
: Number of the extended community list supported by the RR group,
in the range 1 to 199.
Description
Use the
rr-filter
command to create an RR reflection policy.
Use the
undo rr-filter
command to disable the function.
Only IBGP routes whose route target extended community attributes satisfy the matching conditions
are reflected. This provides a way to implement load balancing between RRs.
Examples
# In BGP-VPNv4 subaddress family view, create an RR group and configure it to automatically filter the
incoming VPNv4 route update packets based on the route target extended community attribute.
