The value of vRtrInetAllCidrRouteType indicates the type of route.
Note that 'local' refers to a route for which the next hop is
the final destination; 'remote' refers to a route for which
the next hop is not the final destination.
Routes which do not result in traffic forwarding or
rejection should not be displayed even if the
implementation keeps them stored internally.
'reject' refers to a route which, if matched, discards
the message as unreachable and returns a notification
(e.g. ICMP error) to the message sender. This is used
in some protocols as a means of correctly aggregating
routes.
'blackhole' refers to a route which, if matched,
discards the message silently.
