I found another question that, after I shutdown the ethernet interface
isdn will be up during snapshot pick up isdn.
===================================
but when I use ping to generate the traffic to make the isdn up
the ipx rip will sent to the bri interface,
so that the isdn will not be drop for some period.
So I think that
should I block the rip , sap and other traffic in the ipx access-group under
interface?
not only block in dialer-list ?
but if I block the rip , the router will not update ipx routing during snapshot
?
that will make the router without backup routing via. isdn when backup
ethernet.
As I think next step I should take, I found the isdn drop .
And I have the messages:
*Mar 1 11:47:51: IPXRIP: positing full update to 35.ffff.ffff.ffff via BRI0/0
(
broadcast)
*Mar 1 11:47:51: IPX: Sched upd for BR0/0 (RIP)(FULL): gap = 55, holddown = 5
*Mar 1 11:47:51: IPXRIP: Update for BRI0/0:35 (FULL)(RESET PH)

*Mar 1 11:47:51: ?: 35 via 35:BR0/0 (FULL:BCAST) (SHRZ) NO
*Mar 1 11:47:51: ?: 15 via 35:BR0/0 (FULL:BCAST) YES @[ 7/ 1],
se
nt 0 packet(s)(IDLE)
why these update doesnot trigger isdn up ? why ?
the condition is a little like ip ospf demand-circuit ?
