DES-7200(config-router)# address-family vpnv4
DES-7200(config-router-af)# neighbor 2.2.2.2 active
DES-7200(config-router-af)# neighbor 2.2.2.2 send-community both
DES-7200(config-router-af)# exit
DES-7200(config-router)# address-family ipv4 vrf vpn1
DES-7200(config-router-af)# redistribute ospf 10 vrf vpn1
DES-7200(config-router-af)# exit
DES-7200(config-router)# exit
## Configure route exchanging between PE and CE
DES-7200(config)# router ospf 10 vrf vpn1
DES-7200(config-router)# network 192.168.1.0 0.0.0.255 area 0
DES-7200(config-router)# redistribute bgp 100 subnets
DES-7200(config-router)# exit
Configure CE. Here we will take CE1 as the example. The configurations of CE2 are the same.
DES-7200(config)# interface gigabitEthernet 0/0
# In case of a router, enable fast forwarding on the interface (not applicable to a switch)
DES-7200(config-if)# ip ref
DES-7200(config-if)# ip address 192.168.1.2 255.255.255.0
DES-7200(config-if)# no shutdown
DES-7200(config-if)# exit
DES-7200(config)# router ospf 1
DES-7200(config-router)# network 192.168.1.0 0.0.0.255 area 0
DES-7200(config-router)# exit
2.5.12.5 Verification
# On PE, check routing table entries. Here we will take PE1 as the example. The next-hop
interface of route 2.2.2.2/32 is Tunnel 0.
