looking at my ping'(ipv4)s man page using -g and the IP of the secondary
gateway would work.
using ipv6 i tend to run one rtsold advertisement for each pipe for each
gateway. Thus a host on a network that is comprised of two interconnected
routers with independent access to two shared pipes would have at /least/
4 IPs, thus src address alone is sufficient in the ip6 world!
('local'* services are by fe80:: or rfc 4193 addressing depending upon
segmentation).
* as in LAN or corporate-internal.
