Answer
# 1
RIP-It sends complete routing table to all its active 
interface in evert 30 seconds.Hold down Timer:-it is a time 
during the destination hop is unreachable=240 seconds..

IGRP:-Timer 90 seconds

RIP               
30 Sec(Update)    
180 Sec(Timeout)  
120 Sec(Remove)

   
IGRP  
90 Sec(Update) 
3*Update(Invalid) 
3*Update+10(Hold_down)
7*Update(Flashtime)
         

EIGRP 
For LAN
5 Sec(Hello) 
3*Hello(hold-timer) 

For WAN
60 Sec(Hello) 
3*Hello(hold-timer) 

OSPF
10 Sec(Hello) 
4*Hello(Dead-interval)

RIP-30 Sec Periodically
IGRP-90 Sec Periodically
EIGRP-Only if there is a change in network structure.No
periodically
OSPF-Only Either if there is a change in network structure
or 30 Min Whichever is earliar.

  Re: What are the Timer of RIP, IGRP, EIGRP and OSPF Routing Protocol?
Answer
# 11
RIP,15 seconds.
          (RIP Send routing table to all connected routers)
IGRP,60 seconds.
          (IGRP Send routing table to all connected routers)
EIGRP,
       (After it well converged than If there is a change 
in network structure it will send its routing table to all 
connected routers)

OSPF, It is same as EIGRP.
        (After it well converged than If there is a change 
in network structure it will send its routing table to all 
connected routers)

Answer
# 12
The correct RIP timers as per cisco doc
 
Hellow interval 30 second
dead interval 180
hold down timers 180 second
n flush timers 240 seconds

the eigrp timers
hellow send every 5 second dead 15 second in point to point
in nbma is 60 hellow interval and dead is 180

in ospf 
ppp hellow 10 dead 40
brodcast same 

but in point to multipoing hellow is 30 secon n dead is 120 
second
point multipoint brodcast same
point to multipoint non brodcast

Answer
# 13
Timer given below:-

RIP (Routing Information Protocol):-Route update Timer 
30Sec,
2 Route Invalid n Holdown timer 180 Sec 
3 Flush Out =240 Sec

IGRP (Interior gateway routing protocol):-Route Update 90 
Sec.
2Route Invalid =270 Sec
3 holdown timer = 280 Sec 
4 Flush out timer = 680 Sec


EIGRP (Enhance Interior gateway routing protocol):-For 
1.updatation used HELLO Protocol
2. Toplology used Dual All path entry 
3. Routing Table Best path 

OSPF (Open Shortest path First):-
1. For updation we used HEllo Protocol
2. LSA
Table Best path in N/w

OSPF = (When there is update it send the update part of 
routing)

IGRP = 90 sec

EIGRP = 30 sec
