We are implementing Disaster Recovery Site for our Data Center. Both are located at separate locations. We are using Cisco 6509 Switch as the core switch at DC, running IOS 12.2(18)SXF7,Sup720 in slot 1.We are interconnecting the DC and DR using CWDM fiber link. Now, we need to implement Swith level redundancy between 6509 at Dc and 6509 at DR. This i believe is nothing but redundancy at Sup720 level. I have visited Cisco's site, but could not find clear doc on this. I 'm not sure, if we can use HSRP here, and if yes how and if not, then what will work to create failover.
We have multiple mod in 6509 at both sites, and we also need to impement failover at mod levels as well. Can some body provide guidnace?
