Pushed a version with ":" and bracket for IPV6 rd.route=<net>/<netmask>:<gateway>[:<interface>] Add a static route with route options, which are separated by a colon. IPv6 addresses have to be put in brackets. Example. rd.route=192.168.200.0/24:192.168.100.222:ens10 rd.route=192.168.200.0/24:192.168.100.222 rd.route=192.168.200.0/24::ens10 rd.route=[2001:DB8:3::/8]:[2001:DB8:2::1]:ens10 ^ permalink raw reply [flat|nested] 5+ messages in thread

It's gorgeous. And it includes the cases which only have nexthop address and output interface, that's complete and makes sense.
