Name

Description

Index

Indicates the Index of the OSPF interface.

Metric

Specifies the metric for the type of service (TOS) on this port. The value of the TOS metric is (10^9 / interface speed). The default is 1.

  • FFFF—No route exists for this TOS.

  • IPCP links—Defaults to 0.

  • 0—Use the interface speed as the metric value when the state of the interface is up.

AdvertiseWhenDown

Advertises the network on this port as up, even if the port is down. The default is false.

After you configure a port with no link and enable AdvertiseWhenDown, it does not advertise the route until the port is active. Then, OSPF advertises the route even if the link is down. To disable advertising based on linkstates, disable AdvertiseWhenDown.

IfMtuIgnore

Specifies whether the interface ignores the global maximum transmission unit (MTU) configuration. To allow the switch to accept OSPF database description (DD) packets with a different MTU size, enable MtuIgnore. The interface drops incoming OSPF DD packets if their MTU is greater than 1500 bytes.
