Example: Route Reflection in a VRF Instance
This example demonstrates how to configure BGP route reflection in a VRF instance.
Overview
In the following topology, router RR is a BGP route reflector configured with a VRF instance (VRF1). The VRF
instance is configured with a single IPv4 address family consisting of routers R2 and R3. All three routers belong to
the same autonomous system (AS1).
Figure 32: Route Reflection in a VRF Instance
RR receives BGP routing information from R2 via its VRF interface, 1.1.2.1. It then readvertises the information to
its client, R1.
R2 receives BGP routing information from R3, an external BGP (eBGP) router.
Configuration
To configure this topology, do the following:
1. Configure RR
Configure a VRF definition for VRF1 with a route distinguisher of 100:1. For more information, refer to
