Hi Ibrahim,

If you dont configure a group id, the default value is used.

HSRP groups need to be unique only within the vlan where they are configured.

This implies your config is legitimate as long as you dont use more than one group per vlan and as long as you do not interconnect vlans at layer2.

Hi,

If you have all cisco devices in that network, then your configs will works fine even with same hsrp group number.

If its non-cisco then it doesnt work, the reason is Cisco switches contains mac entries based on vlans where-as non-cisco switches doesn't. Hence same group number should not cause any problems.
