function of VRF OSPF instance. For example: VPN user uses MCE
device to exchange VPN routes with PE. If MCE and PE exchanges VPN
routes via OSPF protocol, to allow the VPN site to learn the routes of
other VPN sites, you must execute "capability vrf-lite" command on
MCE device to disable the loop check function of VRF OSPF instance.
# Disable loop check function of VRF OSPF instance
DES-7200# configure terminal
DES-7200(config)# router ospf 10 vrf vrf1
