Yes, BGP selects only one best bath.
The default for BGP is one path, the default for other routing protocols
is four paths.
However, in some cases you would like to change this for BGP and this can
be acheived using " maximum-paths" command.
The BGP selection process is a series of qualifing steps and if still two
routes were equal then as I recall in step 9( Not sure of the step
number) if you are enabling the maximum-paths command both routes will be
accepted in the routing table.
BTW: This is very unlikely used and most of those using BGP prefer using
other methods to acheive load-balancing rather than using the
"maximum-paths" command.
Regarding static routes, they don't have the wealth of attributes that
BGP has, so if more than one static route is configured to reach a
destination (for example two default routes to different interfaces )they
will be used on a round-robin basis if process switching is enabled.
If fast-switching is used (default) then load-balancing over these equal
static routes will be per destination not per packet like process
switching. Keep in mind that this load-balancing done using via
static-routes only concerns upstream traffic and has nothing to do with
downstream traffic.
