I take that back ....you do need the broadcast piece ...
ospf on isdn does not behave as a point to point frame relay
Larry got a point
this is my config just in case
router 3
interface BRI0
ip address 135.13.99.3 255.255.255.0
encapsulation ppp
ip ospf demand-circuit
dialer idle-timeout 30
dialer map ip 135.13.99.4 name pedro broadcast xxxxxxxxxxxxx
dialer-group 1
isdn switch-type basic-ni
isdn spid1 xxxxxxxxxx10101
isdn spid2 xxxxxxxxxxx0101
ppp authentication chap
end
router 4
interface BRI0
ip address 135.13.99.4 255.255.255.0
encapsulation ppp
ip ospf network point-to-point
ip ospf demand-circuit
dialer idle-timeout 30
dialer map ip 135.13.99.3 name r3 broadcast xxxxxxxxx
dialer-group 1
isdn switch-type basic-ni
isdn spid1 xxxxxxx0101
isdn spid2 xxxxxxx80101
ppp authentication chap
ppp chap hostname pedro
end
