API Guide

If you try to enter an OSPF process ID, or if you try to enable more OSPF processes than available Layer 3 interfaces, prior to
assigning an IP address to an interface and setting the no shutdown command, the following message displays:
Dell(conf)#router ospf 1
% Error: No router ID available.
Assigning a Router ID
In CONFIGURATION ROUTER OSPF mode, assign the router ID.
The router ID is not required to be the router’s IP address. However, Dell Networking recommends using the IP address as the router ID
for easier management and troubleshooting. Optional process-id commands are also described.
• Assign the router ID for the OSPFv2 process.
CONFIG-ROUTER-OSPF-id mode
router-id ip address
• Disable OSPF.
CONFIGURATION mode
no router ospf process-id
• Reset the OSPFv2 process.
EXEC Privilege mode
clear ip ospf process-id
• View the current OSPFv2 status.
EXEC mode
show ip ospf process-id
Dell#show ip ospf 55555
Routing Process ospf 55555 with ID 10.10.10.10
Supports only single TOS (TOS0) routes
SPF schedule delay 5 secs, Hold time between two SPFs 10 secs
Number of area in this router is 0, normal 0 stub 0 nssa 0

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.
