Compares the multi-exit discriminator MED on paths from
different autonomous systems.
Allows load sharing across providers with different (but
equal- length) autonomous system paths. Without this option, the AS paths must
be identical for load sharing.
Compares the router IDs for identical eBGP paths.
Ignores the cost community for BGP best-path calculations.

3 VPN Load Balancing” chapter of the Cisco Nexus 7000 Series NX-OS MPLS
Forces bestpath to do a MED comparison only between paths
originated within a confederation.
Treats a missing MED as the highest MED.
Does not always pick the best MED path from among the paths
from the same autonomous system.
