[Bug 1597979] [NEW] Can not get the advertised routes without using subnet pool
Public bug reported:
After enable the neutron-dynamic-routing, in the case below, the
advertised routes will return null, that is wrong. Note, in this case,
we do not define the address scope, and we just define a subnet pool,
but we do not use it. So considering backward compatibilities, we should
get the advertised routes (destination 10.0.0.0/24, next-hop 172.24.4.2)
