> We need metrics in the homenet protocols to be able to handle this.

Homenet uses Babel for announcing reachability, which has metrics.

Where Homenet is different from what you're used to is that it announces
all available gateways using source-specific routes, and hosts are
supposed to choose the gateway they use (by picking a given source
address).  See


Unless they snoop on Babel traffic, however, hosts have no information
about the metrics associated to individual prefixes.  Snooping on Babel
traffic is not difficult, but it is not defined by the Homenet architecture,
since Homenet requires no host changes.
