OSPF and OSPFv3

M4300 Series and M4300-96X Fully Managed Switches User Manual
5. Select Routing > OSPF > Advanced > OSPF Configuration.
6. In the Router ID field, enter the 32-bit integer in dotted-decimal format that uniquely
identifies the router within the autonomous system (AS).
To change the router ID, you must first disable OSPF. After you set the new router ID, you
must reenable OSPF for the change to take effect. The default value is 0.0.0.0, although
this is not a valid router ID.
7. In the Admin Mode field, select Enable or Disable.
If you select Enable, OSPF is activated for the switch. The default value is Enable.
You
must configure a router ID before OSPF can become operational. For more information,
see Configure the Routing IP Settings on page 291.
8. In the RFC 1583 Compatibility field, select Enable or Disable.
This specifies the preference rules that are used when choosing among multiple
AS-external-LSAs advertising the same destination. If you select Enable, the preference
rules are those defined in Section 16.4.1 of the OSPF-2 standard (RFC 2328), which
prevents routing loops when
AS-external-LSAs for the same destination originated from
dif
ferent areas. The default value is Enable. All routers in the OSPF domain must be
configured the same. If all OSPF routers are capable of operating according to RFC
2328, RFC 1583 Compatibility must be disabled.
9. Set the Opaque LSA Status to Enable if OSPF will store and flood opaque LSAs.
