Isn't a network with mask 32 a host route. So, I think network/gateway/dev > should be enough. > > rd.route=192.168.100.222/32_192.168.1.1_ens10 This is the test environment for this patch. Default gateway goes through eth0, while the kdump target (192.168.200.222) goes through ens10. These 2 NICs are not in the same subnet. For guiding data path, as you said, network/gateway/dev is truly enough. default via 192.168.122.1 dev eth0 proto static metric 1024 192.168.200.0/24 via 192.168.100.222 dev ens10 proto static metric 1 > > > > >> > >> On 27.06.2014 10:08, Baoquan He wrote: > >>> User may specify static route for a target address which is different > >>> than default gateway, hence static route need be added. > >>> > >>> Now add a cmdline parameter rd.route="" and the related operation to > >>> parse it.
