5 # Script for configuring a vif in routed mode.
6 # The hotplugging system will call this script if it is specified either in
7 # the device configuration given to Xend, or the default Xend configuration
8 # in /etc/xen/xend-config.sxp. If the script is specified in neither of those
9 # places, then vif-bridge is the default.
10 #
11 # Usage:
12 # vif-route (add|remove|online|offline)
13 #
14 # Environment vars:
15 # vif vif interface name (required).
16 # XENBUS_PATH path to this device's details in the XenStore (required).
17 #
18 # Read from the store:
19 # ip list of IP networks for the vif, space-separated (default given in
20 # this script).
