Gang,
>From CCO, http://www.cisco.com/warp/public/473/57.html:
"ipx hello-interval eigrp <as-number> <value> : Configures the hello-interval i
n seconds on the interface for the IPX-EIGRP routing process designated by. The
default value is five seconds. This value may set the holding time advertised
in hello packets. The holding time is three times the hello-interval. If the cu
rrent value for the holding time is less than two times the hello-interval, the
holding time will be reset. The default holding time is 15 seconds."
Okay, if I understand this statement, I can configure the hello-interval and th
e hold-time will automatically adjust (providing the old value is less than two
times the new hell-interval)? I've tried this now on four separate sets of in
frastructure, mostly consisting of various 2500 series routers over ethernet se
gments. The standard hello and hold times are 5 sec and 15 sec, respectively.
If I use the command "ipx hello-interval eigrp 1 30" on both EIGRP neighbors o
n the segment, the hold-time does NOT adjust to 90 sec. It stays at 15 sec (sh
ipx eigrp neigh), and what happens is that the neighbors are adjacent for 15 s
ec, hold-time kicks in and drops the adjacency, then 15 sec later anothe hello
packet is seen, so the adjacency re-forms. So instead of the hold-time automat
ically adjusting, you get this up-down neighborship thing going. I've tried re
setting interfaces, restarting routers, same results.
Am I misinterpreting the above statement from Cisco? I'm using code versions 1
2.1(14) on one infrastructure and 12.1(5) on another. Can't remember the code
versions on other sets of infrastructure.
Thanks in advance for the comments.
Andy
