Step
2. Enter BGP view.
3. Configure the PE as a BGP
peer.
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.
