Q: After the VPN instances match the RT mutually, could NE40 transmit direct route and static route directly?
A: It depends on the version of software. VRPv5 differs to VRPv3 in principle. For NE40 at VRPv3, once different VPN instances match RT mutually, the equipment could transmit direct and static routes directly. For NE40 at VRPv5, apart form that VPN instances match their RT mutually, it also needs to configure the MBGP IPv4 address family corresponded to VPN instances. Also, the IPv4 address family should be configured with import-route direct/static command so that both direct and static routes could be transmitted.
