Routing Protocol Timers

Routing Protocol Timers:

RIP

(update timer = 30 sec.) entire routing table 

(invalid timer = 180 sec.) 

(hold-down timer = 180 sec.) 

(flush-down timer = 240 sec.)

IGRP

(update timer = 90 sec.) 

(invalid timer = 270 sec.) 

(hold-down timer = 280 sec.) 

(flush-down timer = 630 sec.)

EIGRP

(5 Sec = Hello timer) 
(3 times Hello = Hold-timer)

(60 Sec. = Hello timer) NBMA less than T1 speed

(3 times Hello = Hold-timer)

(90 Sec. = Update timer)

(3 times Update timer = Invalid timer)

(7 times Update timer = Flush timer)

OSPF

(10 Sec. = Hello timer) 

(30 Sec. NBMA = Hello timer)

(4 times Hello = Dead-interval)

(4 times NBMA Hello = NBMA Dead-interval)
