Use the red bgp <asn> metric transparent command to preserve the RIP metrics.
When RIP routes are redistributed into BGP, the route metric is stored in the BGP MED value.
When BGProutes are redistributed into RIP, and the transparent keyword used, the MED value is
copied back as the RIPmetric. Without the transparent keyword, the metric value specified is
applied to all the routes.
