as you know, i also have not trusted route servers. arnold asked what would allow me to extend a little trust. draft-ymbk-idr-rs-bfd is an attempt. >> clue bat, please. how does your scheme tell the rs to give me next >> best paths instead of those over the failing link? > It doesn't , but then, if the exchange is having issues, I won't be > sending any further traffic over it until it is repaired, so I would > stop trusting the RS at this point. we see many cases of small inter-peer failures where other links are just fine. it can be an interface, a router-to-switch cable, ... this is why we want to tell the rs to back off only the failing link. >> how likely are we to get the bfd hacks from C, J, A, B, ...? in our >> draft, we are trying to minimize dependence on vendor hacks for a >> reason. their frelling bfds are not even fully compatible today. > > This one IMHO requires the least protocol changes (we just register a > new diagnostic flag from an existing IANA FCFS registry), no changes > needed to BGP or the RS implementation. your draft requires changes to bfd. ymbk is trying to avoid that. a hack to bird is something we can do ourselves, does not rely on the vendors. but this is a call for adoption. imiho, the wg should adopt both drafts so we can sort it in the wg. randy
