STUN: AS400 to FEP SDLC

Question

I am having issues in brining up the connectivity between AS400 connecting to FEP using SDLC. I am trying to perform STUN SDLC on the 2800 routers with low speed WAN interfaces facing AS400 and FEP, here is the toplogy;
as400----R1-------R2-------FEP
The links are on Low speed serial interfaces 19.2 Kbps. The interface states are all up/up, but STUN is closed.
AS400 is configured in *SEC role.
Router configs are as follows;
R1 (Router facing AS400)
stun peer-name 192.168.213.32
stun protocol-group 1 sdlc
stun quick-response
(config-if serial 0/0/0)#
description connection to AS/400 SDLC PU 2.1 address C1
mtu 2104
no ip address
encapsulation stun
serial restart-delay 0
clock rate 19200
stun group 1
stun sdlc-role primary
sdlc address C1
stun route address C1 tcp 192.168.213.33 local-ack
R2 (Router facing FEP)
stun peer-name 192.168.213.33
stun protocol-group 1 sdlc
stun quick-response
(config-if serial 0/0/0)#
mtu 2104
no ip address
encapsulation stun
half-duplex
serial restart-delay 0
clock rate 19200
stun group 1
stun sdlc-role secondary
sdlc address C1
stun route address C1 tcp 192.168.213.32 local-ack
Could you please let me know if I am missing anything major in the topology or configurations.
I can also provide AS400 line and FEP configurations if required
thanks

Answer 1

its looks like ok...
i also had configure BSTUN for one of my project but its of multiple BSTUN group because its used for the Frame Relay topology... and i think you need only one group...
just look at this it may help you..
Building configuration...
bstun peer-name 10.1.1.1.
bstun protocol-group 1 async-generic
bstun protocol-group 2 async-generic
interface loopback 0
ip address 10.1.1.1
interface serial1/0
encapsulation frame-relay
interface serial 1/0.1 point-to-point
ip address 20.1.1.1 255.255.255.0
frame-relay interface-dlci 100
interface serial 1/0.2 point-to-point
ip address 20.2.1.1 255.255.255.0
frame-relay interface-dlci 200
interface serial 2/0
physical-layer async
encapsulation bstun
asp role secondary
bstun group 1
bstun route all tcp 30.1.1.1
interface serial 2/1
physical-layer async
encapsulation bstun
asp role secondary
bstun group 2
bstun route all tcp 30.2.1.1
ip route 30.2.1.0 255.255.0.0 20.2.1.2
ip route 0.0.0.0 0.0.0.0 20.1.1.2

end
and its same as for the other end...
