I just need an explanation of the following to fully understand how this configuration works.. I'm guessing it's dealing with HSRP for fail-over of Layer 3 capabilities.. but I'm not sure.. if someone could explain this to me.. piece by piece, I would be most greatful. By the way.. we are running (2) core 6509 boxes (each with dual Sup1/MSFCs in them), trunked to each other.. and (2) access 6509 boxes, each with a trunk to each core (redundant.) So basically.. CORE1 has a trunk to each access box.. and CORE2 has a trunk to each access box. Here is an excerpt of the config on each core box.. (i changed the first 2 octets of the IP.. but i'm guessing that won't matter)
187.2 - CORE2 - routerA
187.3 - CORE1 - routerA
187.4 - CORE2 - routerB
187.5 - CORE1 - routerB
*Note* - When I telnet to 187.1 address.. it brings me into CORE2 - routerA... why??
description Management Subnet

First of all, you wrote that CORE2 Router A - 187.2, but from the configurations I can see that 187.2 is in CORE1 !!! So, when you telnet to 187.1 you are getting into 187.2(core1), which has a higher HSRP priority that 187.3(core2). 187.2 has HSRP priority of 100, 187.3 has HSRP priority of 80 - both of them share the same virtual-IP of 187.1, but as long as both of them up - the 6500 interface vlan 108 with the higher priority will respond.
Use the command " show standby brief" on both 6500s, and you will be able to see for each HSRP group, which router is the master and which router is the standby router.
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
