Babel: Immediately update hello interval on interface reconfigure
An interface reconfiguration may change both the hello and updateintervals. An update interval change is immediately put into effect,while a hello interval change is not. This also updates the hello...

Babel: Do not keep an infeasible route as selected
When a route becomes infeasible it should not be kept as selected; thisis forbidden by section 3.6 of the RFC and prevents subsequent updatesfrom the same router ID from replacing it.
Babel: Send wildcard retractions on shutdown and startup
This makes BIRD send a wildcard retraction on all interfaces beforeshutting down and right after starting up. This helps ensure thatneighbours will discard the announced routes as soon as possible,...
Babel: Rework handling of retractions
An update with wildcard AE and infinite metric should be treated as aglobal retraction of all prefixes announced by that neighbour, persection 4.4.9 of the RFC. In addition, router ID and seqno in retractionupdates should be ignored. This reworks the handling of retractions and...
