Jim,

Either a) bug or b) route selection occurred before the MED was
evaluated.

Does the 151.51.111.111 next-hop route originate from an IBGP peer? Is
it sync'ed? Does the next hop route exist in the IP Routing table?

Regards,

Why is BGP choosing the route to 133.133.133.0 via 151.51.112.2 when it
has a higher metric ?
