The no form of the command deletes the manually configured interface metric, so the interface uses
the computed metric based on the reference-bandwidth command setting and the speed of the
underlying link.
Default no metric — The metric is based on reference-bandwidth setting and the link speed.
Parameters metric — The metric to be applied to the interface expressed as a decimal integer.
Values 1 — 65535
mtu
Syntax mtu bytes
no mtu
Context config>service>vprn>ospf>area>if
Description This command configures the OSPF packet size used on this interface. If this parameter is not
configured OSPF derives the MTU value from the MTU configured (default or explicitly) in the
following contexts:
config>port>ethernet
config>port>sonet-sdh>path
config>port>tdm>t3-e3
config>port>tdm>t1-e1>channel-group
If this parameter is configured, the smaller value between the value configured here and the MTU
configured (default or explicitly) in an above-mentioned context is used.
To determine the actual packet size add 14 bytes for an Ethernet packet and 18 bytes for a tagged
Ethernet packet to the size of the OSPF (IP) packet MTU configured in this command.
Use the no form of this command to revert to default.
Default no mtu — Uses the value derived from the MTU configured in the config>port context.
Parameters bytes — The MTU to be used by OSPF for this logical interface in bytes.
Values 512 — 9198 (9212-14) (Depends on the physical media)
passive
Syntax [no] passive
Context config>service>vprn>ospf>area>if
Description This command adds the passive property to the OSPF interface where passive interfaces are
advertised as OSPF interfaces but do not run the OSPF protocol.
By default, only interface addresses that are configured for OSPF will be advertised as OSPF
interfaces. The passive parameter allows an interface to be advertised as an OSPF interface without
running the OSPF protocol.
