Hi David,

because the different locations have different networks, routers,
IP-addresses etc. But to be always reachable from the outside, they need
one common IP-address, that is valid on the active node.

And only for the active node the 10.20.10.1 is the way to go out, the
passive node does even not have any connectivity to the outside.

There is just a "little hole" for getting updates and for the
pingd-resource needed for the HA-functionality.

This is done by a proxy and/or by routes and it is working as expected.

Well, beside the servers that have to run on the active node, the only
"moving part" is the cluster-ip, it's default route and an additional
route. So I do not see too much complexity?

That might be correct, but this is not the problem I have.


So any other hint what I should do to get the "metric" working for the
route-resources?

Thanks a lot,
