From: nznog-bounces(a)list.waikato.ac.nz [mailto:nznog- bounces(a)list.waikato.ac.nz] On Behalf Of Joel Wiramu Pauling Sent: Wednesday, 13 June 2012 3:25 p.m. To: Andy Linton Cc: nznog(a)list.waikato.ac.nz Subject: Re: [nznog] Reliability & performance of NZ carrier WAN/Internet services ---8<--- L2 effectively is a routed service as it is implemented in the back end these days; "This here L2 Pipe goes to that there L2 pipe WAAAAY over there via XYZ intermediate systems" might as well be routing for all intents and purposes IMHO
There is an important difference though: L2 forwarding is done based on MAC address and L3 forwarding on IP address. L3 forwarding will only pass IP. L2 forwarding will pass (hopefully) any Ethernet frame. This is useful if you want to run anything other than IP, like 802.1ag fault management.
