Assign An Ospfv2 Area; Enable Ospfv2 On Interfaces - Dell Force10 MXL Blade Configuration Manual

In CONFIGURATION ROUTER OSPF mode, assign the Router ID. The Router ID is not required to be
the router's IP address. For easier management and troubleshooting, Dell Force10 recommends using the
IP address as the Router ID.

Assign an OSPFv2 area

After you enable OSPFv2, assign the interface to an OSPF area. To set up OSPF areas and enable OSPFv2
on an interface, use the
You must have at least one AS area: Area 0. This is the backbone area. If your OSPF network contains
more than one area, you must also configure a backbone area (Area ID 0.0.0.0). Any area besides Area 0
can have any number ID assigned to it.
The OSPFv2 process evaluates the
address that is most explicit first to include all subnets of that address. For example, if you assign the
network address 10.0.0.0 /8, you cannot assign the network address 10.1.0.0 /16 because it is already
included in the first network address.
When configuring the

To set up each neighbor and OSPF area, use the following command in CONFIGURATION ROUTER
