show (ospf | ospf3) overview


Syntax (EX Series Switch and QFX Series)


Display Open Shortest Path First (OSPF) overview information.



Display standard information about all OSPF neighbors for all routing instances.

brief | extensive

(Optional) Display the specified level of output.

instance instance-name

(Optional) Display all OSPF interfaces under the named routing instance.

logical-system (all | logical-system-name)

(Optional) Perform this operation on all logical systems or on a particular logical system.

realm (ipv4-multicast | ipv4-unicast | ipv6-multicast)

(Optional) (OSPFv3 only) Display information about the specified OSPFv3 realm, or address family. Use the realm option to specify an address family for OSPFv3 other than IPv6 unicast, which is the default.
