[Int-area] draft-chroboczek-intarea-v4-via-v6 - "IPv4 routes with an IPv6 next hop"

2024-01-22 Thread Warren Kumari
Hi there all, I discovered that I'd somehow misnamed a draft that Juliusz Chroboczek , Toke Høiland-Jørgensen, and myself had written — somehow I'd managed to name it draft-chroboczek-int-v4-via-v6, instead of draft-chroboczek-intarea-v4-via-v6. Anyway, it is targeted at intarea, and so I renamed

Warren, Just to confirm, this is: https://datatracker.ietf.org/doc/draft-chroboczek-int-v4-via-v6/ currently at -02. Correct? I think this is a good idea and support it. I will try to review it and provide more comments. The ICMP behavior is an interesting problem. Bob > On Jan 22, 20

I think the ICMP problem needs to be addressed. Perhaps with an IPv4 option to embed the identity of the router (IPv6 address or some other way to identify the owner). One of the main purposes of traceroute is to identify the router that is dropping packets. It will not be helpful if all the

In many cases, the whole point of using ping and traceroute is to verify that the entire route between nodes works. The PROBE approach doesn’t provide all of the needed functionality. From: Warren Kumari Sent: Monday, January 22, 2024 3:23 PM To: Robinson, Herbie ; Bill Fenner Cc: Internet A

I think this draft is a good idea and I'd like to see it progress. Doing this in Babel worked quite well, and I agree that it makes sense to generalize it. On the topic of source addresses for ICMPv4, I quite liked the Babel solution in RFC 9229 (use any routable v4 address if you have one, otherw

All I have a draft in BESS that uses RFC 8950 and applies it to all BGP AFI/SAFI use case of a single IPv6 peer that can advertise any IPv4 NLRI and as well the converse use case of a single IPv4 peer that can advertise any IPv6 NLRI. https://datatracker.ietf.org/doc/draft-ietf-bess-v4-v6-pe-al
