how i can get it. because if create one Vlan and don't create it's SVI interface it is what i neen but for HSRP feature when i create SVI it starts communication with other VLans.


i also dont want to create access-list to dis-allow inter valn communication.


if there is any solution please help me.

Place the SVI's in a VRF away from your global routing table.

If you don't want to use acl's and you have to have a L3 interface for this new vlan then you can use vrf-lite to separate this vlan from your other vlans. Basically vrf-lite will allow you to have 2 separate routing tables, one for the new vlan and one for the rest.


See this attached link for configuring vrf-lite -

Note the link is for a 4500 config but vrf-lite works on the 6500 as well.
