hello-interval seconds

(Optional) Time (in seconds) between the hello packets that

unsigned integer value to be advertised in the hello packets.

The value must be the same for all routers and access

servers attached to a common network. The default is 10

seconds.

retransmit-interval seconds

(Optional) Time (in seconds) between link-state

advertisement (LSA) retransmissions for adjacencies

attached network. The value must be greater than the

expected round-trip delay. The default is 5 seconds.

transmit-delay seconds

(Optional) Estimated time (in seconds) required to send a

link-state update packet on the interface. The integer value

that must be greater than zero. LSAs in the update packet
