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

Release Information

Command introduced in JUNOS Release 7.4.

realm statement introduced in JUNOS Release 9.2.

Description

Display Open Shortest Path First (OSPF) overview information.

Options

none — Display standard information about all OSPF neighbors for all routing instances on all logical systems.

extensive — (Optional) Display trace information in addition to standard information.

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.

neighbor — (Optional) Display information about the specified OSPF neighbor.

realm (ipv4-multicast | ipv4-unicast | ipv6-multicast) — (ospf3 only) (Optional) Display information about for 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.
