I have a site where there is 5 buildings all with a cross-connect to a MDF. All network routing is working with this poor setup but some network Level 2 leaks happen (DHCP being most common). Is there a way to limit the current bonded interfaces to only work with Level 3 and higher networks to eliminate this problem? Yes a Level 3 Spine switch is the answer but this client does not have the funds to do this so trying to see if can create it based on current setup.
Setup is 5 * CRS125 with 2 bonded links back to the Main CRS125
My theory is limit the bonded links to Level 3 network only. Meaning Level 1 and 2 can only happen within that building but still allow data to move freely across full site on the level 3 and 4.
