Hi:
I found a bug when remove an ip address which is referenced by a routing entry.
step to reproduce:
ip li add type dummy
ip li set dummy0 up
ip ad add 10.0.0.1/24 dev dummy0
ip ad add 10.0.0.2/24 dev dummy0
ip ro add default via 10.0.0.2/24
ip ad del 10.0.0.2/24 dev dummy0
after deleting the secondary ip address, the routing entry still
pointing to 10.0.0.2
# ip ro
default via 10.0.0.2 dev dummy0
10.0.0.0/24 dev dummy0 proto kernel scope link src 10.0.0.1
but actually, kernel considers the default route is directly connected.
# ip ro get 1.1.1.1
1.1.1.1 dev dummy0 src 10.0.0.1
