@TravisFleming1, I believe what you may be seeing is a consequence of asymmetric routing. I’m guessing you have an interface for VLAN 27 on both the MX and MS, and likewise for VLAN 30.   I would suggest you create a transit VLAN between the MX and MS, say VLAN 99 if you’re not already using it. Create VLAN 99 on the MX and a corresponding SVI on the MS stack, and make sure it’s permitted on the trunk between the MX and the MS. Set the default route (0.0.0.0/0) on the MS stack to use the VLAN 99 interface on the MX. Then remove VLAN 27 and VLAN 30 from the MX, so they only have interfaces on the MS stack. You then need to add a static route on the MX for the subnets of VLAN 27 and VLAN 30 with a next hop of the VLAN 99 MS stack SVI.   The only other thing to be aware of is that the management interface on the MS switches can’t be in the same subnet as a Layer 3 interface on the MS. Hopefully all your MS management interfaces are in a separate VLAN and the Layer 3 interface for that VLAN remains on the MX - if not then this is probably a good time to separate them. ... View more
