Explanation
The 'match route-type' command in a route-map is used to identify and match specific types of routes for redistribution. When redistributing routes that are external to the local routing domain - including eBGP-learned routes and routes learned from other IGPs - the keyword 'external' is used. 'match route-type external' matches routes that were learned externally (eBGP routes and routes redistributed from other protocols). Options A and C ('type-1' and 'type-2') are OSPF-specific route types referring to OSPF external LSA types 1 and 2, not a general external route type. Option B ('nssa-external') is specific to OSPF NSSA (Not-So-Stubby Area) routes. Only 'external' broadly covers both external BGP and IGP routes for redistribution purposes.
