Multiple instances of the same route map can be created by assigning a
different sequence number to it. Each instance is identified by the
route map name and the sequence number. The value of the sequence
number associated with the particular route map instance determines the
order in which the routing protocol evaluates routes; the instance of
having lowest sequence number is evaluated first. If the routes pass
all the match conditions specified in the lowest-numbered instance, and
if all set clause elements are successfully configured, then no other
instance of the route map is considered. However, any routes that do
not pass all the match conditions are evaluated against the next
instance of the route map.
