Donny,
I tested it, and turned out the same result as yours- the hold timer did
not change accordingly.
Anyone got a clue?

Hi Frank,
this is how I understand thing.
The hold time will be sent included inside the hello packet (Doyle Routing
TCP/IP page 334), but he
didn't mentioned that the hold time would be automatically calculated by
using the configured hello
interval times 3.
I've tried this on my lab and I can confirmed that at least on IOS 12.1
(13) this is not the case.
I'm not sure of the behaviour on other IOS version, perhaps it's different.
(I've shut down the interface, remove the router eigrp 100 and put it back
again, reload the router,
nothing works).
Do let me know of the test result.

Donny,
EIGRP peer actually build up relationship with hello packets and the
hold down timer is sent within hello packet. At R2 when the hello packets
received from let say R1, R2 will adjust his hold down timer according to
R1's hello timer. Never tested it but should be the way that EIGRP works.
I will test it today and let you know later.

Hi Frank and Jason,
I don't understand how changing the hello timer on one end of the link
(rtrA) can change the hold
time on the adjacent router (routerb). I've tried this on my router with
IOS version 12.1(13),
I've tried with setting the hello on one router to 10 seconds. So if the
solutions works, it should
change the hold time on the other router to 30 right ?
when I do show IP eigrp neigh, and watch the counter for holddown, what I
see is that it get
decremented up to 5 second before it get restored to 14. Meaning the router
still use the default 15
second as the holdtime and wait for the hello for 15 seconds, because the
other end is configured to
send hello every 10 seconds it get decremented for 10 seconds, so it's
correct. But I do not see it
set the holdtime to 30.
Is this IOS related or Is it my understanding on matter ?
RTRA
int e0
ip addr 150.100.23.2 255.255.255.0
ip hello ei 100 10
router eigrp 100
net 150.100.23.0 0.0.0.255
no auto
end
RTRB
int e0
ip addr 150.100.23.3 255.255.255.0
router eigrp 100
net 150.100.23.0 0.0.0.255
no auto
end
Best Regards
Donny
