A.For the cross-domain VPN-OptionB approach, an MP-eBGP neighbor relationship needs to be established between the two ASBRs.

B.For the cross-domain VPN-OptionA mode, the route passed between the two ASBRs is a normal IPv4 route.

C.When the public network tag is LDP only , for cross-domain VPN-optionC scenario 2, a three-layer tag is required in the packet forwarding process.

D.For the cross-domain VPN-OptionB approach, two ASBR-PEs are interconnected with multiple interfaces (including sub-interfaces), each associated with a VPN, each ASBR PE treats the peer as a CE.
