Say i have two Distribution Switches "A" and "B". Switch A is using PVST+ for all Odd Vlan. Switch B is using PVST+ for Even Vlan.
Now I have one Edge Switch "C" connected to both Switches A and B. The current STP priority configuration for Switch A odd vlan is 60 and 61 for Switch B. For HSRP Switch A priority is 90 and 80 for Switch B.
Say we are using odd vlan 299. I know that it will choose Switch A to route all the packets.
1) However, if i swap the HSRP priority configuration of Switch A and B, will Switch C still use Switch A to route the packets?
2) What will be the effect of changing HSRP priority? Will it causes a loop?
