clusterf-ipvs: update Route changes #6

Closed SpComb closed 8 years ago

SpComb commented 8 years ago

Currently the set of active Routes is only applied on Service backend changes. Services also need to be updated if the set of Routes changes, e.g. if a Route for a backend host is withdrawn, then all backends routed via that host should be removed, and vice-versa.

SpComb commented 8 years ago

Fixed with the rewritten config package.
