Cisco Hot Standby Router Protocol Group Virtual Mac Address

1.3.6.1.4.1.9.9.106.1.2.1.1.16

Mac Addresses used are as specified in RFC 2281. For ethernet and fddi interfaces, a MAC address will be in the range 00:00:0c:07:ac:00 through 00:00:0c:07:ac:ff. The last octet is the hexadecimal equivalent of cHsrpGrpNumber (0-255). Some Ethernet and FDDI interfaces allow a unicast MAC address for each HSRP group. Certain Ethernet chipsets(LANCE Ethernet, VGANYLAN and QUICC Ethernet) only support a single Unicast Mac Address. In this case, only one HSRP group is allowed. For TokenRing interfaces, the following three MAC addresses are permitted (functional addresses): C0:00:00:01:00:00 C0:00:00:02:00:00 C0:00:00:04:00:00.
