configure ospf instanceidNEW!

configure ospf instanceid instance-identifier


Configures the Instance Identifier for OSPF instances.

Syntax Description

instance-identifier Specifies the Instance Identifier. Default is 0. Range is 0-255.



Usage Guidelines

RFC 6549 specifies an 8-bit field in the OSPF header by splitting the previous 16-bit Authentication Type field into Instance ID and AuType. If Instance ID is configured, then all OSPF packets sent from the VR will have the Instance ID field set in the packet headers. If Instance IDs in the received packets do not match the configuration of the VR, then the packets will be discarded.


The following example configures an Instance Identifier of 100:

configure ospf instanceid 100
