Hello and thank you for helping us all people!
I have this architecture: Net1 - Router 1 E1 --------------------- E1 Router 2 - Net 2
I am currently using PPP over E1 to bridge Net 1 and Net 2. However I want to remove any overhead contained in the PPP payload. to be exact, I want to remove the Ethernet headers and only leave the IP headers that I carry.
Have you heard of a way to remove bridge/route on layer 3 so no Ethernet headers exists in the PPP payload? Thank you!
Hello snipped-for-privacy@gmail.com,
If you route the traffic all ethernet specific stuff is dropped. When you bridge two LAN's the overhead needs to be intact.
Thank you for your reply Helge. I am not happy about this, but it was nice to know the truth. :-)
Net1 - Router 1 E1 --------------------- E1 Router 2 - Router 3 What I am still trying is to route traffic from Router 3 to Router 2 without Ethernet frames. Router 2 acts as a transparent L2 bridge. I may try a point to point link between Router 2 and Router 3.
So what is the bottom-line issue that you are trying to address ?
Is it bandwidth consumption, latency ... ?
Yes, you are right. :-) The problem is the bandwidth consumption.
By the way, if somebody is wondering how to achieve L2 bridging, here is how: Interface ethernet 0 bridge-group 1
Interface ethernet 1 bridge-group 1
bridge 1 protocol ieee
Of course, you can use serial interfaces or so, instead of ethernet.
Thank you all for reading, del_lover

Nice hint thank you! I am not sure if I am gonna use it, but it is nice anyway.
