Hi,
to not put OSPF demand link up the database must by stable. Make sure,
that not any RIP network is flaping.
The best place to set OSPF demand-circuit is a stub area. If R2 is a
ABR/ASBR you can set "area a0 nssa no-redistribution
default-information-originate" on it.
If R1 is not allowed to authenticate it should not send a challenge
packets. You may set a "ppp authenticate chap callin" command, if R1 is
calling router, or do any authentication on R1 ("no ppp authenticate" -
if turned on).

Subject: isdn - backup - challenge - authentication ???
hi group,
actual i configure some isdn environments for preparing for the lab.
now i'm a littlie confused about what to do and exactly what is the mean
of
the sample questions.
assume the following:
R1-------ethernet--------(ospf)-R2-(RIP)---------------R3 (RIP)
| ospf a0 |
|_______isdn backup_____________|
R1/R2 speaks ospf and R3 only RIP. Distribution is on R2.
Q:isdn should put in ospf area while ethernet between R1/R2 too. The same
area.
isdn shoul act as backup but without the backup statement.
The isdn link should not flap.
also R1 NOT allowed to authenticate.
sometimes i also confused about anything like this: Rx...shoud not
challenge.
what does it mean exactly with not challenge??
first i configure this scenarium without authentication and want to test
ospf demand-circuit.
but the link always stay up and if it go down there comes a broadcast
224.0.0.5 and bring it up.
i think with the demand statement there are no ospf packets about this
link
??
any help ? thanks
udo
