OSPF with the Dell Networking OS
The Dell Networking OS supports up to 16,000 OSPF routes for OSPFv2.
The Dell Networking OS version 7.8.1.0 and later supports multiple OSPF processes (OSPF MP). The FN IOM switch supports up to 16
processes simultaneously.
On OSPFv3, the system supports only one process at a time for all platforms.
Prior to the Dell Networking OS version 7.8.1.0, the system supported one OSPFv2 and one OSPFv3 process ID per system. OSPFv2 and
OSPFv3 can coexist but you must congure them individually.
The Dell Networking OS supports stub areas, totally stub (no summary) and not so stubby areas (NSSAs) and supports the following LSAs,
as described earlier.
• Router (type 1)
• Network (type 2)
• Network Summary (type 3)
• AS Boundary (type 4)
• LSA(type 5)
• External LSA (type 7)
• Link LSA, OSPFv3 only (type 8)
• Opaque Link-Local (type 9)
• Grace LSA, OSPFv3 only (type 11)
