4118 | * queued for every clearing peer, regardless of whether it is | |
4119 | * relevant to the peer at hand. | |
4120 | * | |
4121 | * Overview: There are 3 different indices which need to be | |
4122 | * scrubbed, potentially, when a peer is removed: | |
4123 | * | |
4124 | * 1 peer's routes visible via the RIB (ie accepted routes) | |
4125 | * 2 peer's routes visible by the (optional) peer's adj-in index | |
4126 | * 3 other routes visible by the peer's adj-out index | |
4127 | * | |
4128 | * 3 there is no hurry in scrubbing, once the struct peer is | |
4129 | * removed from bgp->peer, we could just GC such deleted peer's | |
4130 | * adj-outs at our leisure. | |
4131 | * | |
4132 | * 1 and 2 must be 'scrubbed' in some way, at least made | |
4133 | * invisible via RIB index before peer session is allowed to be | |
4134 | * brought back up. So one needs to know when such a 'search' is | |
4135 | * complete. | |
4136 | * | |
4137 | * Ideally: | |
4138 | * | |
4139 | * - there'd be a single global queue or a single RIB walker | |
4140 | * - rather than tracking which route_nodes still need to be | |
4141 | * examined on a peer basis, we'd track which peers still | |
4142 | * aren't cleared | |
4143 | * | |
4144 | * Given that our per-peer prefix-counts now should be reliable, | |
4145 | * this may actually be achievable. It doesn't seem to be a huge | |
4146 | * problem at this time, | |
4147 | * | |
4148 | * It is possible that we have multiple paths for a prefix from | |
4149 | * a peer | |
4150 | * if that peer is using AddPath. | |
