generic routing encapsulation การใช้

Other encapsulation schemes, such as AYIYA or Generic Routing Encapsulation, are also popular.
IETF protocols can be encapsulated recursively, as demonstrated by tunneling protocols such as Generic Routing Encapsulation ( GRE ).
Other software defined interfaces that are treated as directly connected, as long as they are active, are interfaces associated with tunneling protocols such as generic routing encapsulation ( GRE ) or Multi-Protocol Label Switching ( MPLS ).
As an example of network layer over network layer, Generic Routing Encapsulation ( GRE ), a protocol running over IP ( IP protocol number 47 ), often serves to carry IP packets, with RFC 1918 private addresses, over the Internet using delivery packets with public IP addresses.
