AIGP metric to MED translation

Junos OS supports the translation of AIGP metric to MED. You can enable this feature when you want the end to end effective AIGP metric in order to choose the best path. Effective AIGP is the AIGP value advertised with the route plus the IGP cost to reach the nexthop. This is especially useful in Inter-AS MPLS VPNs solution, where customer sites are connected via two different service providers, and customer edge routers want to take IGP metric based decision. You can configure a minimum-aigp to prevent unnecessary update of route when effective-aigp changes past the previously known lowest value. The following configuration statements are introduced at the [edit protocols bgp group metric-out] hierarchy level: 

• effective-aigp to track the effective AIGP metric 
• minimum-igp to track the minimum IGP metric
