How to add redandant core switch catalyst 6513 with less downtime

[Bazoka]

Dears,

I have an existing network with one core switch catalyst 6513 with two supervisor engines, how I can add the redundant core switch with minimum downtime.

before we give right suggestion or advice - what kind of design, you looking to implement.

1. VSS or just another standaone ?

2. is the new kit has same modules as old one which is in production ?

based on the design you looking : 

VSS : 

https://www.cisco.com/c/en/us/support/docs/switches/catalyst-6500-virtual-switching-system-1440/109573-vss-migration.html

if standalone mode :

1. Layer 2 or Layer 3

 - just build the configuration the same as the old one with a new IP management IP address.

 - enable LAG / Port-channel between these 2 core to pass the VLAN if this Layer 2

 - if not make point to point interface with required IGP to exchange routes.

What if I want to make HSRP between both core switches, can you give me a plan need to discuss it with my manager.

Uhhhhh ... what?

If you need to discuss HSRP with your manager then I would recommend hiring a reputable systems integrator to do the work.

If you do not want to make Logically 1 as VSS.

You can extend Layer2 between 2 switches, create a HSRP config.

again depends on how your existing g access switches are connected.
