1) Turning inverse-arp off on physical interface don't turn it off on the
multi-point interface ... can you post outputs of "sh frame-relay map/pvc"
commands. To verify FR Switch and Routers configurations.

2) What does "debug ip packet" and "debug frame-relay packet" output during
the ping?

Hi, Group!

I have a trouble with frame relay. There is next scheme and
configuration:

     r2
   / \
r1 r3
   \ /
     r4

r1:
interface Serial0/0
no ip address
encapsulation frame-relay IETF
no frame-relay inverse-arp
frame-relay lmi-type ansi
!
interface Serial0/0.24 multipoint
ip address 172.16.124.1 255.255.255.0
frame-relay map ip 172.16.124.2 102 broadcast
frame-relay map ip 172.16.124.4 104 broadcast

r2:
interface Serial0/0
no ip address
encapsulation frame-relay IETF
no dce-terminal-timing-enable
no frame-relay inverse-arp
frame-relay lmi-type ansi
!
interface Serial0/0.1 point-to-point
ip address 172.16.124.2 255.255.255.0
frame-relay interface-dlci 201
!
interface Serial0/0.3 point-to-point
ip address 172.16.234.2 255.255.255.0
frame-relay interface-dlci 203

r3:
interface Serial0/0
no ip address
encapsulation frame-relay IETF
no ip route-cache cef
ip split-horizon
no frame-relay inverse-arp
frame-relay lmi-type ansi
!
interface Serial0/0.24 multipoint
ip address 172.16.234.3 255.255.255.0
frame-relay map ip 172.16.234.2 302 broadcast
frame-relay map ip 172.16.234.4 304 broadcast

r4:
interface Serial0/0
no ip address
encapsulation frame-relay IETF
no frame-relay inverse-arp
frame-relay lmi-type ansi
!
interface Serial0/0.1 point-to-point
ip address 172.16.124.4 255.255.255.0
frame-relay interface-dlci 401
!
interface Serial0/0.3 point-to-point
ip address 172.16.234.4 255.255.255.0
frame-relay interface-dlci 403

When I ping the r2 interface from r1 - it's successful, but when I ping
r4 interface from r1 - it's ....
Same scenario with r3 - when I ping r4 - it's success, but when r2 - it's
....

Many thanks,
Max Braun
