How many instance of HSRP group I can configure in Cisco Catalyst 3850 and 4500X ?

PS.: I want know the maximum limit of instance and not the range of group number, If possible, post the link of the documentation.

 

Thanks.

Hi Jean,

  • HSRP version 2 support for IPv4 and IPv6—Improves management and troubleshooting of IP multicast addresses. Also addresses the restrictions in HSRP version 1, such as:

– Group numbers are restricted to the range from 0 to 255. HSRP version 2 expands the group number range from 0 to 4095.

 Multicast address 224.0.0.2 is used to send HSRP hello messages. This address can conflict with Cisco Group Management Protocol (CGMP) leave processing. HSRP version 2 uses the new IP multicast address 224.0.0.102 to send hello packets instead of the multicast address of 224.0.0.2.
