How to extend VLAN in 3rd and 4th 6513 switch with HSRP

[vidhuranjan.gopal]

Hi presently in One Data centre 02 Nos. of 6513 is configured in HSRP. Due to space constraint some servers need to be installed in other room and there 02 Nos of 6509 switches need to be configured in HSRP again. 

One Data Vlan needs to be extended in expanded room. What should be the best practice for configuration in 6509 switches in HSRP. Please suggest.

Just as #1 and #2 are connected with (I would assume) trunking ports, similarly add connections to #3 and #4 Catalyst 6k. Define the layer 2 VLANs in the 6509 and assign access ports to those VLANs as required.

Personally I don't see much value to adding L3 interfaces (SVIs) for the VLANs (and adding them to the HSRP groups) on the 6509s. It depends in part on how your other connectivity into them is setup. If everything leaving the server VLAN goes to users, WAN, Internet etc. via the original pair of 6513s then keep the 6509s simple with only layer 2 VLANs.
