DES-7200 Configuration Guide Chapter 2 Configuring BGP IP VPN
2-78
Create one VRF instance: VPNA . Set the RD and RT values, and associate the VRF with the
corresponding interface.
DES-7200# configure terminal
DES-7200(config)# ip vrf VPNA
DES-7200(config-vrf)# rd 1:100
DES-7200(config-vrf)# route-target both 1:100
DES-7200(config-vrf)# end
# Associate the VRF with an interface.
DES-7200# configure terminal
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 vrf forwarding VPNA
DES-7200(config-if-GigabitEthernet 1/0)#ip address 192.168.10.2 255.255.255.0
DES-7200(config-if-GigabitEthernet 1/0)# end
# Enable BGP and set up MP-IBGP sessions with PE2 and PE3.
DES-7200# configure terminal
DES-7200(config)# router bgp 1

# Configure CE neighbors through EBGP.

# Configure the MPLS signaling on the backbone network and enable MPLS on the public
network interface.
