Hi,
I've seen discussion mentioning the ISDN line is stay up (section 2, task
3), the issue that brought up was the ISDN is up because of the
redistribution of IGRP--->OSPF at R5, and the redistribution of connected in
R6, but both side I've put in the route map to only allow specific route to
be redistributed (at R5, only allow R4 serial 0 network & E0 network to be
redistributed to OSPF, and at R6, only allow R6 serial 0 network to be
redistributed to OSPF using route-map), but the line is still coming up, and
funny is that the even with the demand-circuit configured, "show ip ospf
neig" display that the BRI0 deadtime timer is keep on resetting by Hello
(meaning that timer will not count down to 0, even "sh ip ospf int bri0
state that suppressed hello).
So, I tried taking out all the redistribution route to OSPF at R5 & R6 and
even shut down serial 0 of R4 (make sure IGRP is not running). but the isdn
line is still being brought up by 224.0.0.5
appreciate your help !!!
