3849 | * queued for every clearing peer, regardless of whether it is | |

3851 | * | |
3852 | * Overview: There are 3 different indices which need to be | |
3853 | * scrubbed, potentially, when a peer is removed: | |
3854 | * | |
3855 | * 1 peer's routes visible via the RIB (ie accepted routes) | |
3856 | * 2 peer's routes visible by the (optional) peer's adj-in index | |
3857 | * 3 other routes visible by the peer's adj-out index | |
3858 | * | |
3859 | * 3 there is no hurry in scrubbing, once the struct peer is | |
3860 | * removed from bgp->peer, we could just GC such deleted peer's | |
3861 | * adj-outs at our leisure. | |
3862 | * | |
3863 | * 1 and 2 must be 'scrubbed' in some way, at least made | |
3864 | * invisible via RIB index before peer session is allowed to be | |
3865 | * brought back up. So one needs to know when such a 'search' is | |
3866 | * complete. | |
3867 | * | |
3868 | * Ideally: | |
3869 | * | |
3870 | * - there'd be a single global queue or a single RIB walker | |
3871 | * - rather than tracking which route_nodes still need to be | |
3872 | * examined on a peer basis, we'd track which peers still | |
3873 | * aren't cleared | |
3874 | * | |
3875 | * Given that our per-peer prefix-counts now should be reliable, | |
3876 | * this may actually be achievable. It doesn't seem to be a huge | |
3877 | * problem at this time, | |
3878 | * | |
3879 | * It is possible that we have multiple paths for a prefix from | |
3880 | * a peer | |
