Q in Q MUT size?
As we know , when deploying Q in Q in the network , it may increasing the Ethernet frame size , assume that the L3 packet (L2 payload) is 1500 byte , after adding L2 information (18byte ) , VLAN tag , metro tag. , we actually get a 1526 byte frame . ( I am not sure for this )
My question is what system MTU size should I config?
here is a cisco document :
I confused about the "system MTU" ....
Thanks in advance!
