Interface Metric
The interface metric specifies an integer cost metric (1…9999) for the route. This
metric is used when choosing among multiple routes in the routing table that
most closely match the destination address of a packet being forwarded.
• Use the ipconfig command to identify the IP address of the default
gateway.
• Use the route print command to identify the metric of the default gateway.
If you do not want all network traffic to go through the VPN tunnel, set the
metric of the route though the VPN connection to be larger than the metric of
the route through the default gateway. In the example below, the metric is 10; the
interface field metric must be 11 or greater.
