Re: [spring] packet captures for draft-ietf-spring-srv6-network-programming-06?

Alex, Will try and get you some captures off the devices I've been testing on - in order to make sure I understood this draft properly, and in light of the deployment status draft, I decided to play a lot more deeply and setup a bit of a lab. I'm still doing tests and soon as I have some

Re: [spring] Different MSDs for different traffic types on the same headend.

2019-12-16 Thread Nat Kao
Hi, Jeff. Consider a headend that can perform 1 of the following 2 modes(but not both): 1) Plain IPv4: 6 transport labels + 0 service label => traffic can be steered into a 6-label SR-TE policy. 2) Any type of VPN: 3 transport labels + 1~3 service labels => traffic cannot be steered into a

Thanks Jeff!! Both SR-MPLS & SRv6 in general I am guessing most deployments have been centralized controller based model to take advantage of PCEP and SR-TE policy as necessary automatically instead of statically defined explicit paths. For small deployments I guess you could get away with non

Gyan, MSD is only relevant for a device that either imposes the label stack (head-end) or manipulates it (BSID anchor). There are some other constrains when it comes to entropy labels and ERLD, please read the respective drafts. In general, SID stack would grow when TE is in use (any time you

Pablo, Your point is well-taken. We should remind the reader to abide by *all* RFC 4291 and RFC 8200 validation rules, not just source address validation . I recommend that you make the following change to Section 4.2: OLD> S15. Set the packet's egress adjacency to a member of J S15. Set

Hi, SPRINGers, My comments on SRv6 relate to a worry about modifying packets in transit. In order to better explain myself, or maybe to remove the worry altogether, I would like to ask for packet dumps of SRv6. By looking at the packet contents that go into the network it is much easier to

Hi Ketan, I think Mark is right here. I went through this document again and it seems that it defines endpoint to be used as either "address" or "prefix". See there is nothing wrong with using prefix ... but "address" is normally referred to what is in the packet. Moreover your examples of
