5328 | * queued for every clearing peer, regardless of whether it is | |

5330 | * | |
5331 | * Overview: There are 3 different indices which need to be | |
5332 | * scrubbed, potentially, when a peer is removed: | |
5333 | * | |
5334 | * 1 peer's routes visible via the RIB (ie accepted routes) | |
5335 | * 2 peer's routes visible by the (optional) peer's adj-in index | |
5336 | * 3 other routes visible by the peer's adj-out index | |
5337 | * | |
5338 | * 3 there is no hurry in scrubbing, once the struct peer is | |
5339 | * removed from bgp->peer, we could just GC such deleted peer's | |
5340 | * adj-outs at our leisure. | |
5341 | * | |
5342 | * 1 and 2 must be 'scrubbed' in some way, at least made | |
5343 | * invisible via RIB index before peer session is allowed to be | |
5344 | * brought back up. So one needs to know when such a 'search' is | |
5345 | * complete. | |
5346 | * | |
5347 | * Ideally: | |
5348 | * | |
5349 | * - there'd be a single global queue or a single RIB walker | |
5350 | * - rather than tracking which route_nodes still need to be | |
5351 | * examined on a peer basis, we'd track which peers still | |
5352 | * aren't cleared | |
5353 | * | |
5354 | * Given that our per-peer prefix-counts now should be reliable, | |
5355 | * this may actually be achievable. It doesn't seem to be a huge | |
5356 | * problem at this time, | |
5357 | * | |
