5254 | * queued for every clearing peer, regardless of whether it is | |

5256 | * | |
5257 | * Overview: There are 3 different indices which need to be | |
5258 | * scrubbed, potentially, when a peer is removed: | |
5259 | * | |
5260 | * 1 peer's routes visible via the RIB (ie accepted routes) | |
5261 | * 2 peer's routes visible by the (optional) peer's adj-in index | |
5262 | * 3 other routes visible by the peer's adj-out index | |
5263 | * | |
5264 | * 3 there is no hurry in scrubbing, once the struct peer is | |
5265 | * removed from bgp->peer, we could just GC such deleted peer's | |
5266 | * adj-outs at our leisure. | |
5267 | * | |
5268 | * 1 and 2 must be 'scrubbed' in some way, at least made | |
5269 | * invisible via RIB index before peer session is allowed to be | |
5270 | * brought back up. So one needs to know when such a 'search' is | |
5271 | * complete. | |
5272 | * | |
5273 | * Ideally: | |
5274 | * | |
5275 | * - there'd be a single global queue or a single RIB walker | |
5276 | * - rather than tracking which route_nodes still need to be | |
5277 | * examined on a peer basis, we'd track which peers still | |
5278 | * aren't cleared | |
5279 | * | |
5280 | * Given that our per-peer prefix-counts now should be reliable, | |
5281 | * this may actually be achievable. It doesn't seem to be a huge | |
5282 | * problem at this time, | |
5283 | * | |
5284 | * It is possible that we have multiple paths for a prefix from | |
5285 | * a peer | |
