Title:
マルチプロトコル冗長ルータプロトコルサポート方法及び装置
Document Type and Number:
Japanese Patent JP4744723
Kind Code:
B2
Abstract:
A router is capable of providing multi-protocol redundant router protocol support. The redundant router protocols supported by the router include Hot Standby Router Protocol (HSRP) and Virtual Router Redundancy Protocol (VRRP). The router is capable of supporting multiple groups of virtual routers for each of the redundant router protocols. The router receives a packet and checks for prefix matching of MAC address bits. If the prefix of MAC address matches predefined HSRP or VRRP pattern, the router formulates a key, and compares the key against VRRP/HSRP database. If the key matches, the router routes the packet using virtual router address.
