RE: [Technical Errata Reported] RFC5884 (5085)

2017-08-15 Thread Mach Chen
Hi all, IMHO, the point is not about whether the Echo Reply is optional for a normal LSP Ping, where the echo reply is totally controlled by the reply mode. For RFC5884, since the reply mode is not specified, based on the current text, it can be interpreted as the following two ways: 1) i

Hi Jeff, Huawei's implementation only used dedicated Multicast MAC (when we proposed RFC7130), and did not support the optional behavior. There should be no change since then. Best regards, Mach From: Rtg-bfd On Behalf Of Jeffrey Haas Sent: Thursday, October 20, 2022 8:52 PM To: Reshad Rahman

Hi all, I read the latest version of the draft, it’s well written and easy to read. I think it’s useful solution and ready to move forward. Some nits: - It’s better to expand the abbreviations (e.g., MTU, PDU, etc.) when first use. - s/path MTU/Path MTU (PMTU) when first use

Hi Greg and all, I just have quick review on the drafts. If my understanding is correct, the idea is to use multicast destination address other than unicast address when sending BFD packets over LAG links. And actually this idea has been proposed in https://tools.ietf.org/html/draft-chen-bfd
