LSA delay timer

Each LSA has an age in the local link state database (LSDB) (incremented by one per second), but an LSA

does not age on transmission. You must add an LSA delay time into the age time before transmission,

which is important for low-speed networks.

SPF timer

Whenever the LSDB changes, an SPF calculation happens. If recalculations become frequent, a large

amount of resources are occupied. You can adjust the SPF calculation interval and delay time to protect

networks from being overloaded due to frequent changes.

Supported features

• Basic features defined in RFC 2740

• OSPFv3 stub area

• OSPFv3 multiprocess

• OSPFv3 for VPNs

• BFD

Protocols and standards

• RFC 2740, OSPF for IPv6

• RFC 2328, OSPF Version 2
