yeah ,i got a type mistake in config of int s1/1,i have corrected it.
the config on dte is quite simple ,i think.
It's as follows:
R2:
interface Serial1/1
ip address 172.16.40.1 255.255.255.0
encapsulation frame-relay
router ospf 1
network 172.16.0.0 0.0.255.255 area 0
R3:
interface Serial1/1
ip address 172.16.30.1 255.255.255.0
encapsulation frame-relay
router ospf 1
network 172.16.0.0 0.0.255.255 area 0
from the following result ,the frame swith works ,i think.
and i found the dte routers got DLCI automatically.

****************************
but the ospf seems failed ,R2 and R3 couldn't find each other ,after i add
static route,they got connected.
i don't think we need to run ospf on R1 ,right?
another question is when i run ospf neighbor command ,i got such error,why?
"R2(config-router)#nei 172.16.30.1
OSPF: Neighbor address does not map to an interface"
Thanks.
