3992 | * | |
3993 | * Overview: There are 3 different indices which need to be | |
3994 | * scrubbed, potentially, when a peer is removed: | |
3995 | * | |
3996 | * 1 peer's routes visible via the RIB (ie accepted routes) | |
3997 | * 2 peer's routes visible by the (optional) peer's adj-in index | |
3998 | * 3 other routes visible by the peer's adj-out index | |
3999 | * | |
4000 | * 3 there is no hurry in scrubbing, once the struct peer is | |
4001 | * removed from bgp->peer, we could just GC such deleted peer's | |
4002 | * adj-outs at our leisure. | |
4003 | * | |
4004 | * 1 and 2 must be 'scrubbed' in some way, at least made | |
4005 | * invisible via RIB index before peer session is allowed to be | |
4006 | * brought back up. So one needs to know when such a 'search' is | |
4007 | * complete. | |
4008 | * | |
4009 | * Ideally: | |
4010 | * | |
4011 | * - there'd be a single global queue or a single RIB walker | |
4012 | * - rather than tracking which route_nodes still need to be | |
4013 | * examined on a peer basis, we'd track which peers still | |
4014 | * aren't cleared | |
4015 | * | |
4016 | * Given that our per-peer prefix-counts now should be reliable, | |
4017 | * this may actually be achievable. It doesn't seem to be a huge | |
4018 | * problem at this time, | |
4019 | * | |
4020 | * It is possible that we have multiple paths for a prefix from | |
4021 | * a peer | |
