i have attached the network diagram.
I am using a cisco 4500 switch and a couple of switches
Please help in deciding the type of spanning tree that can be used for this type of network.
Please give me brief idea of configuring spanning tree to aviod loop in the network and faster convergence.
Your help is much appreciated.
you just need to use
spanning-tree mode rapid-pvst
on all switches to enable Rapid PVST.
spanning-tree vlan priority 0
to ensure that it will be the root bridge.
Jon: I didn't see your answer
Hope to help
Thank you for the reply.
The other switches are cisco 2350 switches.
Since i am using cisco 4500 ,should I make the Cisco 4500 as a root bridge
Can you brief me about the Cisco Rapid PVST configuration. for this network.
Your 2350 switches do support Rapid PVST so you should run that between your switches unless you have a very large number of vlans in which case MST is a better option.
From your diagram it would make sense to make the 4500 the STP root for your vlans. Configuring Rapid PVST is very straightforward -
use the above link for config example. Note that the whole chapter may well be worth a read. Key with RSTP is to
1) make sure you enable portfast for all ports connected to end devices
2) make sure you specify point-to-point link type for switch interconnections or alternatively make sure all switch interconnections are running at 100 or 1000 Gbps full duplex.
if the other switches are not Cisco and they support 802.1s MST this should be your better choice.
if all switches are Cisco Rapid PVST can be an easier choice.
Hope to help
