you shouldn't need floating statics or point-to-point interface. OSPF demand
circuit should handle the situation for you-Notice below configuration-
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, * - candidate
default
U - per-user static route, o - ODR, P - periodic downloaded static
route
T - traffic engineered route

Subject: Dial backup for fram-relay point-to-multipoint interface
HI all,
I am facing a problem for configuring frame-relay point-to-multipoint
interface as a backup of isdn bri interface.
Ospf is running on both frame-raly and IP ospf on-demand circuit on
ISDN, the problem is that the PVC down but interface never , so
it cannot dial the isdn bri.
more the restriction are,
1- we have not to used frame-relay point-to-point interface.
2-no floating static route.
Is i can used dialer watch-list for OSPF ???
i read that watch-list is used only for EIGRP and IGRP.
Thanks in advance.
regards,
khalid
