It looks like you mistyped the ospf statements in router 2. Under the ospf
process you specify addresses that have the 2nd octet of .39 when the
interfaces have a second octet of .36. A good way to verify that your
interfaces coincide with your ospf configuration is to do a 'sh ip ospf
int'. This will allow you to verify that the interfaces are configured for
opsf and then you can go into troubleshooting neighbor relationships.

Subject: OSPF Demand Circuit - About to go crazy! :-)
I am beating myself to death with the following:
I am working through the following scenario in which R1 has a Frame Relay
connection to R2 via Frame-Relay and ISDN. R1 is configured with ip ospf
demand-circuit on the ISDN interface as well as OSPF on the Frame Relay
interface. R1 forms an ajacency with R2 over the Frame Relay link, and
they sucessfully exchange databases. R2 is configured the same as R1 with
the exception of the ip ospf demand-circuit, it does not have that
configured. R1 does not show 2 entries in the show ip ospf neighbor
output. R1 and R2 are not forming adjacencies over the OSPF
demand-circuit. I can ping between R1 and R2's BRI interfaces to bring up
the ISDN link, and it works properly, however, if I shut the Frame Relay
interface down, shouldn't the ISDN link come up as both links are in area 0?
R1 has the following relavent configuration:
!
int s0.102 point-to-point
encapsulation frame-relay
ip address 10.36.18.5 255.255.255.252
frame-relay interface-dlci 102
!
int bri0
encapsulation ppp
dialer map ip 10.36.19.5 2222
ip ospf demand-circuit
dialer-group 1
!
router ospf 100
network 10.36.18.5 0.0.0.0 area 0
network 10.36.19.5 0.0.0.0 area 0
!
dialer-list 1 protocol ip permit
R2 has the following relavent configuration
!
int S0.201 point-to-point
encapsulation frame-relay
ip address 10.36.18.6 255.255.255.252
frame-relay interface-dlci 201
!
int bri0
encapsulation ppp
dialer map ip 10.36.19.6 1111
ip ospf demand-circuit
dialer-group 1
!
router ospf 100
network 10.39.18.6 0.0.0.0 area 0
network 10.39.19.6 0.0.0.0 area 0
!
dialer-list 1 protocol ip permit
