swIPv6StaticRouteMetric is the routing metric assigned to a static route, ranging from 1 to 65535 with a default of 1. Admins adjust this value to influence route preference when multiple static routes could reach the same destination, since lower metrics are typically preferred. For example, an admin might set swIPv6StaticRouteMetric to 10 on a backup path so it is used only if the primary route (metric 1) becomes unavailable.
