Troubleshooting - MikroTik RouterOS v2.9 Reference Manual

Example with MikroTik Router to MikroTik Router
Let us consider the following example:
In this example we will use two Moxa C101 synchronous cards.
Do not forget to set line-protocol for synchronous interfaces to frame-relay. To achieve proper
result, one of the synchronous interfaces must operate in DCE mode:
[admin@r1] interface moxa-c101> set 0 frame-relay-dce=yes
[admin@r1] interface moxa-c101> print
Flags: X - disabled, R - running
0 R name="moxa-c101-1" mtu=1500 line-protocol=frame-relay clock-rate=64000
clock-source=external frame-relay-lmi-type=ansi frame-relay-dce=yes
cisco-hdlc-keepalive-interval=10s ignore-dcd=no
[admin@r1] interface moxa-c101>
Then we need to add PVC interfaces and IP addresses.
On the R1:
[admin@r1] interface pvc> add dlci=42 interface=moxa-c101-1
[admin@r1] interface pvc> print
Flags: X - disabled, R - running
# NAME
0 X pvc1
[admin@r1] interface pvc> /ip address add address 4.4.4.1/24 interface pvc1
on the R2:
[admin@r2] interface pvc> add dlci=42 interface=moxa-c101-1
[admin@r2] interface pvc> print
Flags: X - disabled, R - running
# NAME
0 X pvc1
[admin@r2] interface pvc> /ip address add address 4.4.4.2/24 interface pvc1
Finally, we must enable PVC interfaces:
[admin@r1] interface pvc> enable pvc1
[admin@r1] interface pvc>
[admin@r2] interface pvc> enable pvc1
[admin@r2] interface pvc>

Troubleshooting

Description
• I cannot ping through the synchronous frame relay interface between MikroTik router
and a Cisco router
Frame Relay does not support address resolving and IETF encapsulation should be used.
Please check the configuration on the Cisco router
