A.The sham link is a link between two VPN instances. Each VPN instance must have an endpoint address of the sham link, which must be a Loopback with a 32-bit mask in the VPN address space on the PE router. interface address

B.The sham link can be configured in any area and needs to be configured manually, and there must be a route to the sham link destination address (the sham link endpoint address of the peer PE) in the local VPN instance

C.The endpoint address of the sham link is advertised as a VPhv4 address by BGP. Routes that have passed sam1ik can also be imported into BGP in the form of VPNv4 routes

D.In order to forward the VPN flow through the MPLS backbone network, the routing cost of the sham link should be less than the OSPF routing cost of the backdoor road
