Re: [homenet] Selecting a routing protocol for HOMENET

2015-04-01 Thread Fred Baker (fred)
My understanding, which could be wrong, is that the IESG has a long-standing policy that a routing protocol needs to have two interoperable implementations, written from the specification. It’s not about the SDO or the specification (IS-IS anyone?), it’s about having proof that the specification
