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 Z-Series supports up to
3 OSPF processes simultaneously. The S-Series supports up to 16 processes simultaneously.
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)
• AS External (type 5)
