An HSRP group can be assigned an arbitrary group number, from 0 to 255. If you configure
HSRP groups on several VLAN interfaces, it can be handy to make the group number
the same as the VLAN number. However, most Catalyst switches support only up to 16
unique HSRP group numbers. If you have more than 16 VLANs, you will quickly run out
of group numbers. An alternative is to make the group number the same (that is, 1) for
every VLAN interface. This is perfectly valid because the HSRP groups are locally significant
only on an interface. In other words, HSRP Group 1 on interface VLAN 10 is unique
and independent from HSRP Group 1 on interface VLAN 11.
معلش ممكن توضحلى الجزء دا ؟ :confused:
