metric
Syntax metric metric
no metric
Context config>service>vprn>ospf>area>interface
Description
This command configures an explicit route cost metric for the OSPF interface that overrides the
metrics calculated based on the speed of the underlying link.
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.
mtu
Syntax mtu bytes
no mtu
Context config>service>vprn>ospf>area>interface
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:
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.
