Tim,
Why would running RIP over the ISDN connection cause the link to
flap? RIP by default sends updates every 30 seconds and the default
idle-timeout is 120 seconds. If RIP can trigger a call, it will also
reset the idle-timeout before it expires once the link is up.

Subject: Rip over isdn
Hi guys,
If rip is running over an isdn link using ppp encap and the task states
or
implies that that isdn link shouldn't flap, what are the config options
that
should be considered?
Here's my list:
1, ip rip trigger
2. snapshot routing
Given these 2 options, what's the "best" practice? How do I decide
which
option to use?
Also, I think other options such as dialer watch, backup int, etc aren't
good because then, in essence, the isdn link is down unless there's a
problem elsewhere in the network. Do you all agree?
Are there any options I should be considering?
TIA, Tim
