Configuring the MCE that uses OSPF to advertise VPN routes to
the PE
Network requirements
As shown in Figure 4 , the MCE device is connected to VPN 1 through VLAN-interface 10 and is
connected to VPN 2 through VLAN-interface 20. OSPF runs in VPN 2.
Configure the MCE device to separate routes from different VPNs and to advertise the VPN routes to PE
1 through OSPF.

Configuration procedure
Assume that the system name of the MCE device is MCE, the system names of the edge devices of VPN
1 and VPN 2 are VR1 and VR2, and the system name of PE 1 is PE1.
1. Configure the VPN instances on the MCE and PE 1:
# On the MCE, configure VPN instances vpn1 and vpn2, and specify an RD and route targets for
each VPN instance.
