Hi,

I have a few questions regarding the following design below.

If the only vlan which is trunk between the distribution switches is the transit vlan 600 and vlan 600 is also running OSPF. Is there an advantage by also trunking vlan 37 between the switches or is it better just to trunk vlan 37 to the access switch.

Thank you
