I need a quick help from you guys. I am working on network redesign for my company where we are introducing 50 VoIP users and distribution layer. I have done a quick design where I am creating 2 stacks of 3750E's as distibution layer and 3750's for access layer for 50VoIP users. I have attached a topology for the distribution and access layer.
I have confusion over following points:
1). As in the topology shown that two GB Etherchannels between access and distribution, Do I still need to run Rapid PVST between access and distribution for load balancing or we don't need STP at all.
2). Do we still need to use HSRP at distribution layer stacks when access to distribution link is Etherchannel and doing load balancing of VLANs.
3). All servers are connected to core switches in resilient fashion, Do I need to run HSRP on core switches for Server VLANs.
Input to these ASAP would be a great help.
Thx a lot in advance.
