To configure OSPF on a PicOS device, complete the tasks described in the following sections.
Configuring OSPF Router ID
...
set protocols ospf router-id <router-id>
The following example configures 1.1.1.1 as the OSPF router ID:
| Code Block |
|---|
admin@XorPlus# set protocols ospf router-id 1.1.1.1 admin@XorPlus# commit Commit OK. Save done. |
Do not change the router ID after completing the configuration.
Configuring OSPF Areas
Divide an OSPF domain into areas, which contains the flow of most routing protocol traffic within a single area and reduces the impact of protocol on CPU and memory.
Use the following command to configure OSPF areas:
set protocols ospf4 ospf area <area-id> area-type <type>
Area ID 0.0.0.0 is reserved for the backbone and each OSPF domain should must have the backbone area. All traffic between two non-backbone areas must pass through the backbone area. OSPF area types supported by PicOS are: normal, stub, and NSSA. A normal or standard area in OSPF is one that is configured neither as Stub nor NSSA.
The example that follows demonstrates configuration of three different areas:
...
Use the following command to assign a Layer 3 interface to an OSPF area:
set protocol ospf interface <vlan-interface> vif <vlan-interface> interface> area {<ipv4>|<0-4294967295>}
The following commands create Layer 3 VLAN interfaces vlan-2 and vlan-3. The interfaces are given IP addresses and switch ports are assigned to them. Finally, both interfaces are configured to be in the OSPF backbone area according to the table shown below.
