Hi, I have problem with translation Frame Relay to ATM, I will copy my config from ATM router and FR router, ping is ok, I can ping other side perfect but EIGRP all the time do EIGRP - Retry Limit Exceeded. What I missing in configuration ? This is test so i dont have nothing configure about CIR , Bandwith limit itd.. only I need to get that this work and later i will with ISP configure CIR.

Hello Anis,
you can face an MTU mismatch and possibly you need a protocol command on atm side
int atm1/0
mtu 1500
interface ATM1/0.50 point-to-point
pvc Unitic 2/50
protocol ip 192.168.1.2 broadcast
Hope to help

I try this what you say but I still get same problem:
Oct 17 19:40:18.368: %DUAL-5-NBRCHANGE: IP-EIGRP(0) 10: Neighbor 192.168.1.2 (Serial0/0/0.50) is down: Interface Goodbye received
Oct 17 19:40:18.596: %DUAL-5-NBRCHANGE: IP-EIGRP(0) 10: Neighbor 192.168.1.2 (Serial0/0/0.50) is up: new adjacency

Hello Anis,
do you see these two lines all the time ?
verify that the frame-rel pvc is stable with
sh frame-rel pvc
and on atm side
sh atm pvc
try to perform an extended ping to qualify the link.
I would add on each side something to advertise
r1
int loop1
ip address 192.168.1.111 255.255.255.255
router eigrp 10
network 192.168.1.111 0.0.0.0
r2 atm side
int atm1/0.50
mtu 1500
int loop1
ip address 192.168.1.112 255.255.255.255
router eigrp 10
network 192.168.1.112 0.0.0.0
use debug ip eigrp hello
Hope to help

When I change on side Freame relay interface on this kind of config , then seems like its ok. But when i use point to pontt then eigrp is down,
FR side:
interface Serial0/0/0
ip address 192.168.1.2 255.255.255.252
encapsulation frame-relay IETF
frame-relay map ip 192.168.1.2 50 broadcast
frame-relay map ip 192.168.1.1 50 broadcast
frame-relay interface-dlci 50
frame-relay lmi-type ansi
ATM side :
interface ATM1/0.50 multipoint
ip address 192.168.1.1 255.255.255.252
pvc 2/50
protocol ip 192.168.1.1
protocol ip 192.168.1.2 broadcast

Ok so now work like this:
FR side:
interface Serial0/0/0
ip address 192.168.1.2 255.255.255.252
encapsulation frame-relay IETF
frame-relay map ip 192.168.1.2 50 broadcast
frame-relay map ip 192.168.1.1 50 broadcast
frame-relay interface-dlci 50
frame-relay lmi-type ansi
ATM side :
interface ATM1/0.50 multipoint
ip address 192.168.1.1 255.255.255.252
pvc 2/50
protocol ip 192.168.1.1
protocol ip 192.168.1.2 broadcast
but how to make work on point to point ?
if work like this then i type some wrong commands and point to point not work.
thanks for any help ppl

Hello Anis,
it looks like that when using point-to-point FR to ATM service interworking does not transport the multicast ip over the FR DLCI: it is the atm side that does not receive and then sends the goodbye message to close the session
try
int ser0/0/0
int ser0/0/0.50 point-to-point
frame-relay interface-dlci 50
frame-relay map ip 192.168.1.1 50 broadcast
! if the second is not allowed remove the first and put only the second
or try to use neighbor commands under the router eigrp process on both routers
router eigrp 10
neighbor 192.168.1.2
router eigrp 10
neighbor 192.168.1.1
in this way you instruct the routers to use unicast packets to exchange hellos and updates
Hope to help
