Re: [OSPF] OSPF Hybrid Broadcast and P2MP Interface Type

Pete,

Good point on the "different types of transmission technologies".

BTW, I made a mistake for the draft link. It should be http://www.ietf.org/internet-drafts/draft-nsheth-ospf-hybrid-bcast-and-p2mp-01.txt

Thanks.
Jeffrey

Hi,

There is also a case of multiple ethernet switches connected together serially, with varying propagation delays to the routers that are connected to one of these switches. Imagine different types of transmission technologies in the network but still having ethernet on each end of the links.

>From the perspective of a router connected to the nearest switch, a router on a far end switch will have higher propagation delay than a router connected to the same (nearest) switch, so having the ability to define a higher OSPF metric to that far end router can become important.

Thanks,
pete

Hi,

I presented the draft http://www.ietf.org/draft-nsheth-ospf-hybrid-bcast-and-p2mp-01.txt in Beijing (slides http://www.ietf.org/proceedings/79/slides/ospf-9.ppt) and it was deferred to the mailing list on whether the problem is worth the working group effort (some who reviewed the draft agreed that the proposed solution is reasonable for the problem).

I'd like to request folks to review the draft/slides and voice your opinion. We developed the solution for a real network situation and would like to see that it gets consensus and standardized so that more operators/vendors can benefit from this.

Thanks.
Jeffrey
