OSPF and OSPFv3
436
M6100, M5300, and M7100 Series Managed Switches
This specifies the estimated number of seconds it takes to transmit a link state update
packet over the selected interface. The valid values range from 1 to 3600 seconds (1
hour). The default value is 1 second.
17. Configure MTU Ignore by selecting Enable or Disable from the list.
MTU Ignore disables OSPF MTU mismatch detection on receiving database description
packets. The default value is Disable (MTU mismatch detection is enabled).
18. Configure Passive Mode by selecting Enable or Disable from the list.
Make an interface passive to prevent OSPF from forming an adjacency on an interface.
OSPF advertises networks attached to passive interfaces as stub networks. Interfaces
are not passive by default, meaning that the passive mode default is Disable.
19. Set the OSPFv3 Network Type on the interface by selecting either Broadcast or
Point-to-Point Mode from the list.
OSPFv3 selects a designated router and originates network LSAs only for broadcast
networks. No more than two OSPFv3 routers can be present on a point-to-point link. The
default network type for Ethernet interfaces is Broadcast.
20. In the Metric Cost field, enter the value for the cost Type of Service (TOS).
OSPF uses this value in computing shortest paths. The range is from 1 to 65,535. The
default is 1. Metric Cost is configurable only if OSPFv3 is initialized on the interface.
21. Click the Apply button.
The updated configuration is sent to the switch. Configuration changes take effect
immediately.
The following table describes the nonconfigurable data that is displayed.

Field Description
IPv6 Address The IPv6 address of the interface.
LSA Ack Interval (secs) The number of seconds between LSA acknowledgment packet
transmissions, which must be less than the retransmit interval.
State
(continued on the next page)
The current state of the selected router interface. State is one of the
following:
• Down. This is the initial interface state. The lower-level protocols
indicate that the interface is unusable. Interface parameters are set to
their initial values. All interface timers are disabled, and there are no
adjacencies associated with the interface.
