Dear Friends,
just wanted to know after googling for hours..
is it possible for us to have redundancy of 2 host servers attached to 2 diff C6500s ?
flex links wil not work here,
STP wont work as there are hosts( or can we add switches to make it work)..
these 2 servers are video streamers attached to 2 diff c6500s and will be streaming the same channels , so need to have 1 server "off" on the switch and to be the back-up of the active server.
awaiting eagerly
Shukla.

Hi!
I had a look into your drawing. I would do it like this. L2 between the C6500, then on the C6500-A port to Streamer-A you configure
int gi0/1
description Streamer-A
ip address 192.168.0.2 255.255.255.0
standby 1 ip 192.168.0.1
standby 1 priority 110
stanbdy 1 preempt
standby 1 name StreamerApair
on C6500-B on port connected to Streamer-A backup:
int gi0/1
description Streamer-A
ip address 192.168.0.3 255.255.255.0
standby 1 ip 192.168.0.1
standby 1 name StreamerApair
* IP addresses and interface are just as example
then on the streamers A and A-backup you put the default gateway 192.168.0.1
All the traffic will flow from Streamer A through C6500-A, and in case that link broke you have the other one streaming.
The same for Streamer-B. If you need full mesh redundancy (Streamer A connected directly to both C6500-A and B, it can be done if you have enough interfaces and with a litlle more complex configuration).
Good luck!

Sorry I wasn't paying attention to the title. The solution below is for L3
Hi!
If the ports connected to the servers are L3 you can use HSRP with higher priority on one port (let's say the one connected to server 1)
and all the traffic will flow through there. Also the standby IP will have to be the gateway for the servers.
Since I don't know the topology I'm only guessing that this solution should fit.
