vpn interface gre—Configure a GRE tunnel interface interface in the transport VPN (on vEdge routers only).
GRE interfaces are logical interfaces, and you configure them just like any other physical interface. GRE interfaces come up as soon as they are configured, and they stay up as long as the physical tunnel interface is up.
