For the inter-domain vPN-OptionB, the ASBR MP-eBGP mode needs to establish a neighbor relationship.

For the inter-domain vPn -OptionA, the routes of the ASBR IPv4 mode are ordinary inter-route routes.

For inter-domain vPN-OptionB, ASBR-E ( ), VPN, two methods, use multiple interfaces, including sub-interfaces, interconnect each interface, one each.
