4397 | * | |
4398 | * Overview: There are 3 different indices which need to be | |
4399 | * scrubbed, potentially, when a peer is removed: | |
4400 | * | |
4401 | * 1 peer's routes visible via the RIB (ie accepted routes) | |
4402 | * 2 peer's routes visible by the (optional) peer's adj-in index | |
4403 | * 3 other routes visible by the peer's adj-out index | |
4404 | * | |
4405 | * 3 there is no hurry in scrubbing, once the struct peer is | |
4406 | * removed from bgp->peer, we could just GC such deleted peer's | |
4407 | * adj-outs at our leisure. | |
4408 | * | |
4409 | * 1 and 2 must be 'scrubbed' in some way, at least made | |
4410 | * invisible via RIB index before peer session is allowed to be | |
4411 | * brought back up. So one needs to know when such a 'search' is | |
4412 | * complete. | |
4413 | * | |
4414 | * Ideally: | |
4415 | * | |
4416 | * - there'd be a single global queue or a single RIB walker | |
4417 | * - rather than tracking which route_nodes still need to be | |
4418 | * examined on a peer basis, we'd track which peers still | |
4419 | * aren't cleared | |
4420 | * | |
4421 | * Given that our per-peer prefix-counts now should be reliable, | |
4422 | * this may actually be achievable. It doesn't seem to be a huge | |
4423 | * problem at this time, | |
4424 | * | |
4425 | * It is possible that we have multiple paths for a prefix from | |
4426 | * a peer | |
