Explanation

Cisco NX-OS supports HSRP version 1 by default. You can configure an interface to use HSRP HSRP version 2 has the following enhancements to to HSRP version 1: - Expands the group number range. HSRP version 1 supports group numbers from 0 to 255. HSRP version 2 supports group numbers from 0 to 4095. - Uses the new IP multicast address 224.0.0.102 to send hello packets instead of the multicast address of 224.0.0.2, which is used by HSRP version 1. - Uses the MAC address range from 0000.0C9F.F000 to 0000.0C9F.FFFF. HSRP version 1 uses the MAC address range 0000.0C07.AC00 to 0000.0C07.ACFF. - Adds support for MD5 authentication. When you change the HSRP version, Cisco NX-OS reinitializes the group because it now has a new virtual MAC address. HSRP version 2 has a different packet format than HSRP version 1. The packet format uses a type-length-value (TLV) format. HSRP version 2 packets received by an HSRP version 1 router os/unicast/configuration/guide/l3_cli_nxos/l3_hsrp.html#wp1220382
