I have to extend my vlan via L3 I found good info about how to do it, https://community.cisco.com/t5/switching/vlan-extend-on-l3-link/m-p/2738682#M331832 , but i have some questions, I have my switch where I will do the configs to exented the vlan, here is no issue, the issue is on the remote switch (ISP) what will they have to change so this config will work?
thanks.
