Deploying CSM in Bridge Mode into an existing server envronment

We have installed two CSM's in a 6509's in a network that has servers already in an existing subnet and vlan.My question is.Can I use the same vlan that the servers are on at this time for the server slb vlan or do I have to create another server slb vlan in the subnet?

Re: Deploying CSM in Bridge Mode into an existing server envronm

the servers can stay in the same vlan.

But if you want bridge mode, you will need to configure 2 vlans in the CSM using the same subnet.

1 vlan will be the same as the servers.

The 2nd vlan will be a new vlan using the same ip subnet.

The MSFC should be setup with only the 2nd vlan.

So at the end you get

MSFC---VLAN-A----CSM-----VLAN-B----SERVERS

<-------------- one subnet --------------->

The servers can keep the same gateway ip address.

This ip address should be moved from current msfc vlan to the newly created vlan.

[I say MSFC, but it could be any other router being currently the default gateway]

Thanks Gilles for your input this has been an on going discusion in our group.I have one question,in reading about CSM configuration modes the term MFSC side vlan and CSM side vlan is used.Is the MFSC side vlan the one that is configured with the vlan interface the SVI? Thanks for your help.
