4. Create the BGP IPv4 unicast
family and enter its view.
5. Enable IPv4 unicast route
exchange with the specified
peer or peer group.
6. (Optional.) Configure route
redistribution.
Configuring IBGP between a PE and a CE
Use IBGP between PE and CE only in a basic MPLS L3VPN network. In networks such as
Hub&Spoke, Extranet, inter-AS VPN, carrier's carrier, nested VPN, and HoVPN, you cannot use
IBGP between PE and CE.
1. Configure the PE:
Step
1. Enter system view.
2. Enter BGP view.
3. Enter BGP-VPN instance
view.
4. Configure the CE as the VPN
IBGP peer.
5. Create the BGP-VPN IPv4
unicast family and enter its
view.
6. Enable IPv4 unicast route
exchange with the specified
peer.
7. Configure the CE as a client
of the RR.

By default, the BGP IPv4
unicast family is not created.
By default, BGP does not
exchange IPv4 unicast
routes with any peer.
A CE must redistribute its
routes to the PE so the PE
can advertise them to the
peer CE.

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.
By default, no BGP peer is
created.
By default, the BGP-VPN
IPv4 unicast family is not
created.
By default, BGP does not
exchange IPv4 unicast
routes with any peer.
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.
