Hi Group, Well I have a slight confession to make. When I initially asked the question, it was based on the assumption that Cisco provided this. But they don't. I had played with bridging over frame relay way back, and somehow this became GRE in my mind. Sorry about the mistake.
So now im looking into L2TP as an alternative. But the One-Access 1221 & 1424 are supporting ethernet over GRE.

This sounds like what Cisco is doing with OTV. They are using ethernet over GRE w/multicast to transport ethernet... It is being marketed as a better alternative to VPLS. ________________________________ From: Pekka Savola <[email protected]> To: Patrik Olsson <[email protected]> Cc: "[email protected]" <[email protected]> Sent: Thu, June 3, 2010 4:59:26 AM Subject: Re: [j-nsp] GRE & Bridging, is it possible with a Juniper box ?

Dont remeber the rfc, but is not supported by Juniper. Only > supported by a small Latvian vendor I think... I wonder if you refer to rfc3378. I recall support for it was recently added in Linux as well. But I don't see why encapsulaitng whole ethernet frames in GRE could not work if vendors just chose to support it. Then as 'ether type' in GRE header you could put 0x6558 or 0x8100 (IEEE 802.1q VLAN-tagged frames *). The former is also supported in Linux [http://lwn.net/Articles/303062/] *) http://www.iana.org/assignments/ethernet-numbers -- Pekka Savola "You each name yourselves king, yet the Netcore Oy kingdom bleeds."
