Example: Clusters in Clusters
This example demonstrates how to group clusters into a hierarchical structure (clusters of clusters).
Overview
In the following topology, a route reflector (RR1) forms a cluster with two other route reflectors (RR2 and RR3).
RR2 and RR3 are also part of their own individual clusters, each of which consists of three clients.
Figure 31: Hierarchical Clusters Topology
When an external BGP (eBGP) router (R1) advertises routes to RR1, RR1 readvertises the routes to RR2 and RR3. RR2
and RR3 then readvertise the routes again to their clients.
Configuration
To configure this topology, do the following:
1. Configure the clusters for RR2 and RR3. For more information, refer to
Device as a Route
2. Configure RR1 as a route reflector and define RR2 and RR3 as its clients. For more information, refer to
