Hello @joe97 

ROAS is good!

But you have to adjus SW_CORE trunk itnerfaces config!

Gig 1/1 to 5/1 should be in mode trunk! not mode access !

So on the switches on the other side, ensure that is a trunk port as well ! Allowed only the vlan id you need to propagate on Trunks !

any issues with inter-vlan and roas, make sure trunk is up and is allowing vlans. also make sure u have vlan x on all switches that need it - even transit ones.
