This patch adds support for adding a static route for
a network. The "via" specifies the gateway's IP
address. Both IPv4 and IPv6 static routes are
supported although it is expected that this
functionality will have more use with IPv6.
Extensive tests are done to validate that the input
definitions are correct. For example, for a static
route ip definition, the address must be for a network
and not a host. Additional checks are added to ensure
that the specified gateway has a network defined on
this bridge.
Whan a static route is added to a bridge, there is a slight
possibility that the gateway address will be incorrect. If
this is handled as an error, that bridge becomes unusable and
can only be recovered by rebooting. If the error is
ignored, then that network can be destroyed and the network
definition file edited to correct the problem. Unfortunately,
the error message only appears in syslog. However, with
the checks performed when the network definition file is parsed,
it is unlikely that this condition will ever occur.
The command used is of the following form:
ip route add <address>/<prefix> via <gateway> dev <virbr-bridge> \
proto static metric 1
.
