CDP neighbor trouble. (Question #14)

Consider a small network like the one below

Router1 ----[FR cloud]---- Router2

The configurations on the two routers are as below

Router1

interface Serial2
no ip address
encapsulation frame-relay
no keepalive
!
interface Serial2.2 multipoint
ip address 150.150.100.1 255.255.255.0
frame-relay interface-dlci 102


Router2

interface Serial2
no ip address
encapsulation frame-relay
no keepalive
!
interface Serial2.2 multipoint
ip address 150.150.100.2 255.255.255.0
frame-relay interface-dlci 201


The routers can ping each other over the frame relay interfaces. However a "show cdp neighbor" on each router shows nothing even though CDP has not been disabled in the configuration. What needs to be done to cause these two routers running IOS to see each other as CDP neigbors over the frame relay link?

Comments:
I think the answer is to give interfaces an address, CDP will be able to relate to. ( interfaces have no ip)
