Enabling Multi-Process OSPF (OSPFv2, IPv4 Only)
Multi-process OSPF allows multiple OSPFv2 processes on a single router.
For more information, refer to Multi-Process OSPF (OSPFv2, IPv4 Only)
When configuring a single OSPF process, follow the same steps previously described. Repeat them as often as necessary for the
desired number of processes. After the process is created, all other configurations apply as usual.
1. Assign an IP address to an interface.
CONFIG-INTERFACE mode
ip address ip-address mask
Format: A.B.C.D/M.
If you are using a Loopback interface, refer to Loopback Interfaces.
2. Enable the interface.
CONFIG-INTERFACE mode
no shutdown
3. Return to CONFIGURATION mode to enable the OSPFv2 process globally.
CONFIGURATION mode
router ospf process-id [vrf]
The range is from 0 to 65535.
After the OSPF process and the VRF are tied together, the OSPF process ID cannot be used again in the system.
If you try to enable more OSPF processes than available Layer 3 interfaces, the following message displays:
Dell(conf)#router ospf 1
% Error: No router ID available.
Assigning an OSPFv2 Area
After you enable OSPFv2, assign the interface to an OSPF area. Set up OSPF areas and enable OSPFv2 on an interface with
the network command.
You must have at least one AS area: Area 0. This is the backbone area. If your OSPF network contains more than one area,
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 network commands in the order they are configured. Assign the network 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 network command, configure a network address and mask that is a superset of the IP subnet configured
on the Layer-3 interface for OSPFv2 to use.
You can assign the area in the following step by a number or with an IP interface address.
● Enable OSPFv2 on an interface and assign a network address range to a specific OSPF area.
CONFIG-ROUTER-OSPF-id mode
network ip-address mask area area-id
The IP Address Format is A.B.C.D/M.
The area ID range is from 0 to 65535 or A.B.C.D/M.
