In case a static route is resolving over multiple nexthops (multipath), if the first nexthop in the list is recursively resolving over a blackhole, zebra does not bother looking at other nexthops and sends a netlink update to the kernel marking the route as a blackhole. This results in complete traffic blackholing even in a multipath setup. If number of nexthops > 1, do not bother checking for recursively resolved blackhole nexthop. Let zebra's multipath handling take over. Signed-off-by: Abhishek Naik <[email protected]>
