I googled erspan0

but I dont know exactly for what is it

[SOLVED]How to remove interface erspan0?

Hi all! on my virtual router, on Openwrt 18.06.4, appeared interface erspan0. I know that it can be used to copy traffic inside the network, but I do not want to use it, and I want to delete this interface, how to do it? p.s. I installed openwrt out of the box, and maybe mistakenly installed some kmod, question which one?... [1tmp]
