Hi After configuring interfaces and routes, and triggering a 'service
netif restart && service routing restart' is there a way to wait for the
'carrier up' of the interface before route reconfiguration? My use case
is a server with 2 Mellanox and a Lagg. The 2 mce interfaces are UP in
milliseconds but the lagg interface takes a few seconds to be UP, and
the routing service says 'Network unreachable'. The subnet is a /32 and
the gateway need a static route like: # /etc/rc.conf.d/netif
cloned_interfaces="lagg0" ifconfig_mce0="up" ifconfig_mce1="up"
ifconfig_lagg0="laggproto lacp laggport mce0 laggport mce1 198.51.100.1
netmask 255.255.255.255 mtu 1500" # /etc/rc.conf.d/routing
route_defaultgw="-host 203.0.113.1 -link -interface lagg0"
defaultrouter="203.0.113.1" static_routes="defaultgw" If I run 'service
netif restart && sleep 5 && service routing restart', everything is ok.
I didn't find any options for that, and was thinking about a patch in
the routing script. Thanks
