4744 | * queued for every clearing peer, regardless of whether it is | |
4745 | * relevant to the peer at hand. | |
4746 | * | |
4747 | * Overview: There are 3 different indices which need to be | |
4748 | * scrubbed, potentially, when a peer is removed: | |
4749 | * | |
4750 | * 1 peer's routes visible via the RIB (ie accepted routes) | |
4751 | * 2 peer's routes visible by the (optional) peer's adj-in index | |
4752 | * 3 other routes visible by the peer's adj-out index | |
4753 | * | |
4754 | * 3 there is no hurry in scrubbing, once the struct peer is | |
4755 | * removed from bgp->peer, we could just GC such deleted peer's | |
4756 | * adj-outs at our leisure. | |
4757 | * | |
4758 | * 1 and 2 must be 'scrubbed' in some way, at least made | |
4759 | * invisible via RIB index before peer session is allowed to be | |
4760 | * brought back up. So one needs to know when such a 'search' is | |
4761 | * complete. | |
4762 | * | |
4763 | * Ideally: | |
4764 | * | |
4765 | * - there'd be a single global queue or a single RIB walker | |
4766 | * - rather than tracking which route_nodes still need to be | |
4767 | * examined on a peer basis, we'd track which peers still | |
4768 | * aren't cleared | |
4769 | * | |
4770 | * Given that our per-peer prefix-counts now should be reliable, | |
4771 | * this may actually be achievable. It doesn't seem to be a huge | |
4772 | * problem at this time, | |
4773 | * | |
4774 | * It is possible that we have multiple paths for a prefix from | |
4775 | * a peer | |
4776 | * if that peer is using AddPath. | |
