Hi, Chris: Until now, I haven’t heard you, and also other experts for the technical analysis of UPDATED big-TLV solution(https://datatracker.ietf.org/doc/draft-wang-lsr-isis-big-tlv/) Lack of such technical analysis, any subjective conclusion is untenable. It’s same as declaring again and agai

Hi, Les:From its publication on September 2014, RFC 7356 has been existing 10 years, can you give some examples that which vendor has implemented it, which operator has deployed it?Don’t you think RFC7356 is one failure RFC? Why encourage other persons to solve the problem based on such RFC?MP-TLV

And given that there are multiple LSPs per node, the IS-IS MTU limit is only for a single top-level TLV. Should this become a problem, we already have some experience with TLV/sub-TLV concatenation 😉 > On Nov 1, 2024, at 12:12 PM, Les Ginsberg (ginsberg) > wrote: > > Robert – > Your comments

Robert – The need for more than 255 bytes/TLV in this case has nothing to do with “non-routing-protocol-data”. It is required because we have a need for more than 255 bytes of data directly used by the protocol. Please do not conflate this with issues related to requests for the IGPs to carry

Thx Les ! I asked this 2nd time as IMO direction towards growing TLV sizes is not the best solution. Especially for opaque to routing information which applies to (tiny) subset of link state nodes in the IGP domain. See if you keep bringing larger and larger trucks folks will happily keep loadin
