正确答案: （1）VRRP is an IEEE standard （RFC 2338） for router redundancy； HSRP is a Cisco proprietary protocol.
（2）VRRP allows actual router IP address to be the same with the virtual IP，and if the same the router which get the IP will become Master router of the VRRP group；HSRP do not allow actual router IP address to be the same with the virtual IP.
（3）HSRP uses the multicast address 224.0.0.2 which represent all router in the subnet ， while VRRP uses the multicast address 224.0.0.18；HSRP uses UDP port 1985 while VRRP uses a protocol number of 112.
（4）HSRP may have one active router，one standby router，multiple listening router.While VRRP may have one master router，multiple backup router.
