Renumber & consolidate HSRP groups?

paulwoodsy

I have a large number of SVI's on my distribution switches & I'd like to ensure they are being packet switched using cef.

The MSFC in use houses a PFC2 daugther board which can only accomodate up to 16 HSRP group instances before routing overheads kicks in.

I have breached this quota, so I would like to renumber & consolidate these HSRP group instances without causing an impact?

Any advice on how best to prepare this bearing in mind I can't allow any service impact?

Thanks in advance.

Hello Paul,

I'm afraid you have already performed your migration.

However, without impact is not possible as the change of HSRP group leads to a change of the VIP MAC address unless using standby use-bia but I don't know if this supported on your platform.

you can change one SVI per time. this is possible

Hope to help

Giuseppe
