Configuring Neighbors as Route Reflector Clients
BGP devices can act as route reflector
clients, or as route reflectors (RRs). You can configure a BGP peer as an RR client
from the
device that is going to reflect the routes and act as the RR. The following task
configures
a specified neighbor to act as an RR client for the BGP L2VPN EVPN address family
- Enter global configuration mode.
- Enable BGP routing.
- Configure the autonomous system number (ASN).
- Specify the ASN for the neighbor device.
- Enable BGP L2VPN EVPN address family configuration mode.
- Activate the neighbor to enable the exchange of information.
- Enable the sending of both standard and extended attributes in updates to the specified BGP neighbor.
- Configure a neighbor to act as
an RR client. A neighbor with the IP address 10.1.1.35 is configured to act as an RR client for the BGP L2VPN EVPN address family.
The following example configures a neighbor with the IP address 10.1.1.35 to be act as an RR client for the BGP L2VPN EVPN address family.
