Hi,
We are using cisco core switch RPVST mode.
we normally enabled Root-guard on CoreSwitch trunk port connected to access switch
From Access switch port connected with Core switch, we enable loop-guard
Query is " do we need to enable loop-guard in between x-connect of core switches, as per loop-guard definition - Loop guard must be enabled on the non-designated ports (more precisely, on root and alternate ports) for all possible combinations of active topologies
In my case , For even vlan core switch 1 is root, odd vlan core switch 2 is root.
from Core 1
VLAN0904 Desg FWD 2 128.130 P2p
VLAN0995 Root FWD 2 128.130 P2p
From Core 2
VLAN0904 Root FWD 2 128.130 P2p
VLAN0995 Desg FWD 2 128.130 P2p

It won't hurt if you configure loopguard on all ports. You can even enable loopguard globally by issuing spanning-tree loopguard default.

Hi,
What will be the pros/cons of the same when we enable loop-guard in x-connect
