2. Enter BGP view.
bgp as-number N/A
3. Enter BGP-VPN instance
view.
ip vpn-instance
vpn-instance-name
Configuration commands in
BGP-VPN instance view are the
same as those in BGP view. For
more information, see Layer
3—IP Routing Configuration
Guide.
4. Configure the CE as the VPN
IBGP peer.
peer { group-name | ip-address }
as-number as-number
By default, no BGP peer is
created.
5. Create the BGP-VPN IPv4
unicast family and enter its
view.
address-family ipv4 [ unicast ]
By default, the BGP-VPN IPv4
unicast family is not created.
6. Enable IPv4 unicast route
exchange with the specified
peer.
peer { group-name | ip-address }
enable
By default, BGP does not
exchange IPv4 unicast routes
with any peer.
7. Configure the CE as a client
of the RR.
peer { group-name | ip-address }
reflect-client
By default, no RR or RR client is
configured, and the PE does not
advertise routes learned from the
IBGP peer CE to other IBGP
peers, including VPNv4 IBGP
peers. The PE advertises routes
learned from the CE to other
IBGP peers only when you
configure the IBGP peer CE as a
client of the RR.
Configuring an RR does not
change the next hop of a route.
To change the next hop of a
route, configure an inbound
policy on the receiving side.
8. (Optional.) Enable route
reflection between clients.
reflect between-clients
Route reflection between clients
is enabled by default.
9. (Optional.) Configure the
cluster ID for the RR.
reflector cluster-id { cluster-id |
ip-address }
By default, the RR uses its own
router ID as the cluster ID.
If multiple RRs exist in a cluster,
use this command to configure
the same cluster ID for all RRs in
the cluster to avoid routing loops.
