Hi Rene,
in your VRRP section you mention 16 groups maximum for HSRP.
In your HSRP section https://networklessons.com/cisco/ccnp-switch/hsrp-hot-standby-routing-protocol/ you say 0 – 255 (HSRPv1) and 0 – 4095 (HSRPv2).
It seems that this is an individual number depending on the hardware model. Right ?
When researching further i found following:
3550 - 16 groups
3750 - 32 groups
On following document for 3850
it says:
You can configure up to 128 groups at the configuration level but the recommended HSRP group number limit is 64.
Routers seem to be capable of up to 255 (HSRPv1) and 4095 (HSRPv2).
So this doesn’t seem to be fixed value at least not for switches. It seems to be dependent on the platform.
Could you please confirm or correct me ?
Many thanks,
Oliver
