MCE configuration examples

Example: Configuring the MCE that uses OSPF to advertise
VPN routes to the PE

Network configuration

As shown in

, VPN 2 runs OSPF. The edge devices of VPN 1 and VPN 2 are VR 1 and VR 2,

respectively. Configure the MCE device to separate routes from different VPNs and to advertise the
VPN routes to PE 1 through OSPF.

Figure 4 Network diagram

Procedure

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.
