Definition: Virtual Router Redundancy Protocol.
Action: between a plurality of gateways (interfaces) runs, forming a backup gateway, and load balancing layer 3 forwarding data.
Gateway role / status: master: It should be, at most, can only appear one by. For forwarding user data packets.
backup: There may be multiple.
master election principles: First, prioritized, the bigger the better; the default is 100;.
2. Secondly, compare the IP address, the bigger the better;
configuration: must run on the gateway interface;
both sides must be identical configuration commands, in addition to priority Configuration.
Troubleshooting: multiple master.
