Implementing OSPF with FTOS
FTOS supports up to 10,000 OSPF routes. Within that 10,000 up to 8,000 routes can be designated as
external and up to 2,000 designated as inter/intra area routes.
FTOS version 7.8.1.0 and later support multiple OSPF processes (OSPF MP). The S-Series supports up to
16 processes simultaneously. The Z-Series supports up to three OSPF processes simultaneously.
Prior to 7.8.1.0, FTOS supports 1 OSPFv2 and 1 OSPFv3 process ID per system. Recall that OSPFv2 and
OSPFv3 can coexist but must be configured individually.
FTOS supports Stub areas, Totally Stub (No Summary) and Not So Stubby Areas (NSSAs) and supports
the following LSAs, as discussed earlier in this document.
• Router (type 1)
• Network (type 2)
• Network Summary (type 3)
• AS Boundary (type 4)
