I have 2 6509 switches, with dual supervisor modules. They are currently connected to each other via an etherchannel trunk.
I am still running a class b subnet, but will be changing to class c, and using vlans on the switches.
I intend on using hsrp standby groups on the switches for maximum redundancy.
Can I assume the following config?
CatA_supA interface vlan1 ip address 192.168.1.250 255.255.255.0 standby 1 priority 200 preempt standby 1 ip 192.168.1.254
CatA-supB interface vlan1 ip address 192.168.1.251 255.255.255.0 standby 1 priority 160 preempt standby 1 ip 192.168.1.254
CatB_supA interface vlan1 ip address 192.168.1.252 255.255.255.0 standby 1 priority 140 preempt standby 1 ip 192.168.1.254
CatB-supB interface vlan1 ip address 192.168.1.253 255.255.255.0 standby 1 priority 120 preempt standby 1 ip 192.168.1.254
As I am using the standby group number on all routers, they all form part of the same hsrp group? How do the hsrp groups talk to each other
- is it using hello ?
I also presume, that any client on either Cat will use the higher priority interface, even if it's on the other Cat?
Is this a good/valid configuration, or is there a better simpler way to do it?
My thought is that this provides me with a good redundancy, as if the primary supervisor goes down, the 2nd will take over, or if an entire switch goes down, the remaining one can support the default gateway? I would stagger the priorities of the various vlans across the switches/router modules evenly.
Many thanks all....
