Pie ChartsHi everybody
Up until now I've been practicing all related to DDR and I think I've nailed
almost anything (would appreciate a challenge in this matter :P ) but I got
one question.
In almost all the books I've read (Solies, Caslow etc) they always advise
you to be careful when using link state protocols in ISDN because updates
might trigger a call and keep the link up indefinitely, their one an only
recommendation is to use " passive interface Bri X" command under the
routing protocol, I know that by doing this I'll be losing the capability
of learning routes trough the Bri interfaces when the link is up and I would
have to relay on static routes (not the case on OSPF Demand circuit), so my
question is as fallow, why haven't this authors consider the use of denying
the routing protocol (in dialer-list) to trigger a call? would a proctor in
the actual lab consider this method less sophisticated or "an easy way out"?
is there any side effects or consideration in using this method.
Thanks a lot for your comments.
Regards,
Ludwig
