We currently have a single 6509 chassis with redundant Sup720 modules. We just purchased a second 6509, and will be moving the secondary Sup720 to this chassis.
I would like to know the "best practices" for setting this up:
1: Inter-switch links - configuration for communication between chassis (4 x Gigabit copper interfaces)
2: Reconfigure from "single-gateway" routing to HSRP, without disrupting client access.
(can HSRP be set to use ~50% active routed links on one chassis, and ~50% on the other chassis?)
3: Redundant links from external switches (one link to each 6509, both operational?)
(Note that most external switches have multiple VLANS associated with them, routed and non-routed)
I understand most of the concept, but would like to "fill in the blanks", so to speak, before we start this project.
Any ideas, issues, noted problems, and/or configuration examples would be appreciated. Especially, any "gotchas" that caused problems in making this type of change.
Thanks in advance.
