HSRP in 1 Cat6500?

Hi All,

In Cisco's doc about 6500, there is a statement:

"To use HSRP, you must have one of the following configurations:

Two supervisor engines in a single chassis (redundant supervisor engines)---each supervisor engine must have both an MSFC and PFC installed.

Two supervisor engines in two chassis---you must have one supervisor engine, equipped with an MSFC and PFC, in each chassis."

So does it mean that the 2 supervisor engines are active in the same time? Because HSRP need two routers are active except there is 1 fail. But it seems impossible because I remember that just 1 supervisor can be active in 1 chassis.If I can do that, it's no use to config RPR because I can use HSRP in 1 chassis to load-balance for multiple VLANs.

Anybody knows about that? Thank you!

Best Regards

When using HSRP between MSFCs in a chassis, both MSFCs are indeed active. Note however that this is only at layer-3. If you're using CatOS at layer-2, for example, CatOS considers one Supervisor to be active and one standby.

So does it mean that in Native IOS of 6500, 2 supervisor engines in 1 6500 chassis can be active at the same time? I can not find the information in the web site. Thank you!

Best Regards
