I just started managing network that has 2 Core Switches connecting various Distribution Layer switches etc.
The core switches are also doing Inter-VLAN Routing and configured with Active\Standby VLAN interfaces with SW-1 having ALL the Active interfaces and configured for preempt.
However in the spanning tree configuration SW-1 and SW-2 are configured with the same bridge priority (8192) for ALL VLANs. These result is that SW-2 is now the Root for majority of the VLANs.
Does this effect network performance considering that SW-1 is doing ALL the routing while SW-2 is Root for all those VLANs ?
Does it make sense to configure the Bridge priority on SW-2 to 16384 for All VLANs so that SW-1 is the Root ?
Could there be a good reason to configure same Bridge Priority on both Core switches ?
