To clarify this a bit, "bgp deterministic med" allows the use of MEDs during
path selection among multiple peers to the same sub-AS in a confederation.
The "bgp always-compare-med" command does what's described below in addition
to enabling the use of MEDs within a confederation; however, the neighboring
sub-ASes can be different unlike when using "bgp deterministic med" alone.

// Normally, MED is only compared between routes received from one AS.
//
// For example,if you are AS 1400 and you have 3 WAN connections. 2 of those
// are to UUNET (AS701) and one is to AS1300. If you receive the route for say
// 209.224.0.0 from all three connections, BGP will only use MED to compare the
// 2 routes from UUNET, but not from AS1300. That command will have the router
// compare MEDs from different AS's, in this case AS701 and AS1300.
