There is no command to choose to send or not the bgp4-mibv2 traps.
Since the MIB bgp4-mibv2 notification are redundant with MIB RFC4273
we added a command:
- [no] bgp snmp traps bgp4-mibv2
By default, the bgp4-mibv2 traps will be disabled, to prevent from
redundancy.
This commit add the support of traps for bgp4-mibv2.
It is conformant to draft-ietf-idr-bgp4-mibv2-11.
The following traps are supported:
- bgp4V2EstablishedNotification
- bgp4V2BackwardTransitionNotification
There is no cli command to prevent the router to send traps
implemented in the rfc4273. If not done, when introducing
the traps from bgp4v2mib, traps will be send for each of
the two mibs: there will be redundancy in the sent information.
Add a new command:
- [no] bgp snmp traps rfc4273
Using this command will allow or not the notification of
the following traps:
- bgpEstablishedNotification
- bgpBackwardTransNotification

zebra: Allow longer prefix matches for nexthops
Zebra currently does a shortest prefix match for
resolving nexthops for a prefix. This is typically
an ok thing to do but fails in several specific scenarios.
If a nexthop matches to a route that is not usable, nexthop
resolution just gives up and refuses to use that particular
route. For example if zebra currently has a covering prefix
say a 10.0.0.0/8. And about the same time it receives a
10.1.0.0/16 ( a more specific than the /8 ) and another
route A, who's nexthop is 10.1.1.1. Imagine the 10.1.0.0/16
is processed enough to know we want to install it and the
prefix is sent to the dataplane for installation( it is queued )
and then route A is processed, nexthop resolution will fail
and the route A will be left in limbo as uninstallable.
Let's modify the nexthop resolution code in zebra such that
if a nexthop's most specific match is unusable, continue looking
up the table till we get to the 0.0.0.0/0 route( if it's even
installed ). If we find a usable route for the nexthop accept
it and use it.
The bgp_default_originate topology test is frequently failing
with this exact problem:
B>* 0.0.0.0/0 [200/0] via 192.168.1.1, r2-r1-eth0, weight 1, 00:00:21
B 1.0.1.17/32 [200/0] via 192.168.0.1 inactive, weight 1, 00:00:21

B>* 198.51.1.2/32 [20/0] via 192.168.2.2, r2-r3-eth1, weight 1, 00:00:32
Notice that the 1.0.1.17/32 route is inactive but the nexthop
192.168.0.1 is covered by both the 192.168.0.0/24 prefix( shortest match )
*and* the 0.0.0.0/0 route ( longest match ). When looking at the logs
the 1.0.1.17/32 route was not being installed because the matching
route was not in a usable state, which is because the 192.168.0.0/24
route was in the process of being installed.

This was true when we had only a CLI for configuration. Now mgmtd has a

they can send invalid requests that lead to errors.
This is still true for CLI though, so the same comment still stays in

bgpd: Do not suppress conditional advertisement updates if triggered
If we have a prefix-list with one entry, and after some time we append a prefix-list
with some more additional entries, conditional advertisement is triggered, and the
old entries are suppressed (because they look identical as sent before).
Hence, the old entries are sent as withdrawals and only new entries sent as updates.
Force re-sending all BGP updates for conditional advertisement. The same is done
for route-refresh, and/or soft clear operations.

- replace all /* fallthrough */ comments with portable fallthrough;
pseudo keyword to accomodate both gcc and clang
- add missing break; statements as required by older versions of gcc
- cleanup some code to remove unnecessary fallthrough

The weight scale value might be useful to have it

Let's start that process

nhrpd: Fix nhrp_peer leak
- Addressed memory leak by removing `&c->peer_notifier` from the notifier list on termination. Retaining it caused the notifier list to stay active, preventing the deletion of `c->cur.peer`
thereby causing a memory leak.
- Reordered termination steps to call `vrf_terminate` before `nhrp_vc_terminate`, preventing a heap-use-after-free issue when `nhrp_vc_notify_del` is invoked in `nhrp_peer_check_delete`.
- Added an if statement to avoid passing NULL as hash to `hash_release`, which leads to a SIGSEGV.

We may receive some xxxCHAIN netlink messages, but we ignore
them (currently). Add them to the basic handler callback so
that we don't log errors about them.
