5281 | * | |
5282 | * Overview: There are 3 different indices which need to be | |
5283 | * scrubbed, potentially, when a peer is removed: | |
5284 | * | |
5285 | * 1 peer's routes visible via the RIB (ie accepted routes) | |
5286 | * 2 peer's routes visible by the (optional) peer's adj-in index | |
5287 | * 3 other routes visible by the peer's adj-out index | |
5288 | * | |
5289 | * 3 there is no hurry in scrubbing, once the struct peer is | |
5290 | * removed from bgp->peer, we could just GC such deleted peer's | |
5291 | * adj-outs at our leisure. | |
5292 | * | |
5293 | * 1 and 2 must be 'scrubbed' in some way, at least made | |
5294 | * invisible via RIB index before peer session is allowed to be | |
5295 | * brought back up. So one needs to know when such a 'search' is | |
5296 | * complete. | |
5297 | * | |
5298 | * Ideally: | |
5299 | * | |
5300 | * - there'd be a single global queue or a single RIB walker | |
5301 | * - rather than tracking which route_nodes still need to be | |
5302 | * examined on a peer basis, we'd track which peers still | |
5303 | * aren't cleared | |
5304 | * | |
5305 | * Given that our per-peer prefix-counts now should be reliable, | |
5306 | * this may actually be achievable. It doesn't seem to be a huge | |
5307 | * problem at this time, | |
5308 | * | |
5309 | * It is possible that we have multiple paths for a prefix from | |
5310 | * a peer | |
