I have an ethernet device in my lan with a primary address 192.168.5.205
and a secondary address .217. I added the secondary address after network
startup established the primary address by an ip addr add command:
# ip addr add 192.168.5.217/24 broadcast 192.168.5.255 dev eth0
# ip addr show
...
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast qlen 1000
link/ether 78:2b:cb:23:21:4c brd ff:ff:ff:ff:ff:ff
inet 192.168.5.205/24 brd 192.168.5.255 scope global eth0
inet 192.168.5.217/24 brd 192.168.5.255 scope global secondary eth0
inet6 fe80::7a2b:cbff:fe23:214c/64 scope link
valid_lft forever preferred_lft forever
...
Then I add a new route via a network gateway but I want the route to use
the secondary address as a source.
# ip route add 11.11.11.11 via 192.168.5.148 src 192.168.5.217
And the ip route show command shows that it knows the source.
# ip route show
11.11.11.11 via 192.168.5.148 dev eth0 src 192.168.5.217
But where is the source address kept? If I look at /proc/net/route,
it shows the route (0B0B0B0B = 11.11.11.11), but not the source
address.
# cat /proc/net/route
