Redistributes OSPF routes from one routing domain to
another routing domain.
or
Redistributes OSPFv3 routes from one routing domain to
another routing domain.
• This command causes the router to become an ASBR
by definition.
• OSPF tags all routes learned through redistribution as
external.
• The protocol and its process ID, if it has one, indicate
the protocol being redistributed into OSPF.
• The metric is the cost you assign to the external route.
The default is 20 for all protocols except BGP, whose
default metric is 1.
• The OSPF example redistributes BGP autonomous
system 1, Level 1 routes into OSPF as Type 2 external
routes.
• The OSPFv3 example redistributes BGP autonomous
system 1, Level 1 and 2 routes into OSPF. The external
link type associated with the default route advertised
into the OSPFv3 routing domain is the Type 1 external
route.
Note RPL is not supported for OSPFv3.
