Hmmm, look at this then:
access(BRI0/0)<--->(BRI0/0)core
*******************8
ACCESS
!
interface BRI0/0
ip address 1.1.1.1 255.255.255.252
encapsulation ppp
dialer string 111
dialer-group 1
isdn switch-type basic-net3
!
dialer-list 1 protocol ip permit
!
****************
CORE
!
interface BRI0/0
ip address 1.1.1.2 255.255.255.252

isdn switch-type basic-net3
****************
ACCESS
1.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
C 1.1.1.0/30 is directly connected, BRI0/0
