3829 | * queued for every clearing peer, regardless of whether it is | |

3831 | * | |
3832 | * Overview: There are 3 different indices which need to be | |
3833 | * scrubbed, potentially, when a peer is removed: | |
3834 | * | |
3835 | * 1 peer's routes visible via the RIB (ie accepted routes) | |
3836 | * 2 peer's routes visible by the (optional) peer's adj-in index | |
3837 | * 3 other routes visible by the peer's adj-out index | |
3838 | * | |
3839 | * 3 there is no hurry in scrubbing, once the struct peer is | |
3840 | * removed from bgp->peer, we could just GC such deleted peer's | |
3841 | * adj-outs at our leisure. | |
3842 | * | |
3843 | * 1 and 2 must be 'scrubbed' in some way, at least made | |
3844 | * invisible via RIB index before peer session is allowed to be | |
3845 | * brought back up. So one needs to know when such a 'search' is | |
3846 | * complete. | |
3847 | * | |
3848 | * Ideally: | |
3849 | * | |
3850 | * - there'd be a single global queue or a single RIB walker | |
3851 | * - rather than tracking which route_nodes still need to be | |
3852 | * examined on a peer basis, we'd track which peers still | |
3853 | * aren't cleared | |
3854 | * | |
3855 | * Given that our per-peer prefix-counts now should be reliable, | |
3856 | * this may actually be achievable. It doesn't seem to be a huge | |
3857 | * problem at this time, | |
3858 | * | |
3859 | * It is possible that we have multiple paths for a prefix from | |
3860 | * a peer | |
