DES-7200 Configuration Guide Chapter 2 Configuring BGP IP VPN
2-100
Refer to the configuration procedure in Running BGP Between a PE and CE to Transmit VPN
Routes and the related configurations in Intranet Configuration Examples.
# Configure the MPLS signaling on the backbone network and enable MPLS on the public
network interface.
DES-7200# configure terminal
DES-7200(config)# mpls ip
DES-7200(config)# mpls router ldp
DES-7200(config-mpls-router)# ldp router-id interface loopback 0 force
DES-7200(config-mpls-router)# exit
DES-7200(config)# interface gigabitethernet 1/0
# The no switchport command is used to switch the port mode on switches to routed port mode.
It is not applicable to routers. You are not required to run this command on routers.
DES-7200(config-if-GigabitEthernet 1/0)# no switchport
DES-7200(config-if-GigabitEthernet 1/0)# ip address 20.20.20.1
255.255.255.0
DES-7200(config-if-GigabitEthernet 1/0)# label-switching
DES-7200(config-if-GigabitEthernet 1/0)# mpls ip
DES-7200(config-if-GigabitEthernet 1/0)# end
# Configure routing protocols on the backbone network.
DES-7200# configure terminal
DES-7200(config)# router ospf 10
DES-7200(config-router)# network 20.20.20.0 0.0.0.255 area 0
DES-7200(config-router)# network 1.1.1.1 0.0.0.0 area 0
DES-7200(config-router)# end
The procedure of PE1-AS2 is similar to the preceding one.
P1-AS1:
# Configure the loopback interface.
DES-7200# configure terminal
DES-7200(config)# interface loopback 0
DES-7200(config-if-Loopback 0)# ip address 2.2.2.2 255.255.255.255
