CSM: Is it possible to access IPv4 server farms via IPv6 vIP?
Before we start a more extensive testing programme I would like to ask the experts whether or not it should be possible to access already existing server farms (with IPv4 vIP) via an additional IPv6 vIP configured on the load balancer.
The system in question is 6509 with Sup720 and CSM WS-X6066-SLB-APC.
The idea is simple: Take an existing server farm (running completely on v4) and add an additional v6 vIP on the load balancer without the need to change the actual v4 networking behind the load balancer.
Might this work (at least for some protocols like http, ftp, etc.)?
Any "yes" or "no" or "maybe" or "with restrictions" appreciated.;)

Fairly sure this isn't possible. Unless I've missed something, the CSM doesn't support IPv6 at all. Even if it did, I don't think a v6 VIP to a v4 real would work. The only place I've seen this work was on a NetScaler, because the NetScaler holds independent connections open to the client and to the servers as a HTTP proxy, passing the request between the two. I forget how the ACE operates; it may be able to act as a proxy, but don't think it supports v6 either.
v6 support on CSMs would be totally awesome, but I'm not holding my breath.
