1. I have the attached Network Switch setup in our office.i am just new to this place and trying to understand the topology.we have more than 25 vlans in our network and VTP enbaled in it.manually spanning-tree root switch has not been configured hence it took the lowest mac-address bearing switch as its root switch which is very old switch. do we face any issue/latency in reaching other subnet through this root switch?
2. Right now we dont have IP phones in our network. we use Nortel PBX with phone. now our company has decided to implement Avaya IP phones in our network. with this current set up can i implement IP phones in our network.can we enable QOS in this switches? Do we need to create separate Vlan for Voice?
1- I wouldnt keep it like this, for Optimal design and Network path flow, the appropriate is to set the Root Switch to be at the distribution layer, following the CISCO three Hierarchical design. Since you have only CORE and the Core acting as a distribution , i will set the root bridge to be that switch. its also capable interms of device hardware capability.
2- Yes, you need to configure a single vlan to be used for voice communication, and you would need to implement QoS if you have bandwidth limitation or if you want to gurantee latency for Voice traffic.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
