Synchronous Link Application Examples

MikroTik Router to MikroTik Router
Let us consider the following network setup with two MikroTik Routers connected to a leased line
with baseband modems:
The driver for MOXA C101 card should be loaded and the interface should be enabled according to
the instructions given above. The IP addresses assigned to the synchronous interface should be as
follows:
[admin@MikroTik] ip address> add address 1.1.1.1/32 interface wan \
\... network 1.1.1.2 broadcast 255.255.255.255
[admin@MikroTik] ip address> print
Flags: X - disabled, I - invalid, D - dynamic
# ADDRESS
0 10.0.0.254/24
1 192.168.0.254/24
2 1.1.1.1/32
[admin@MikroTik] ip address> /ping 1.1.1.2
1.1.1.2 64 byte pong: ttl=255 time=31 ms
1.1.1.2 64 byte pong: ttl=255 time=26 ms
1.1.1.2 64 byte pong: ttl=255 time=26 ms
3 packets transmitted, 3 packets received, 0% packet loss
round-trip min/avg/max = 26/27.6/31 ms
[admin@MikroTik] ip address>
The default route should be set to the gateway router 1.1.1.2:
[admin@MikroTik] ip route> add gateway 1.1.1.2
[admin@MikroTik] ip route> print
Flags: X - disabled, I - invalid, D - dynamic, J - rejected,
C - connect, S - static, R - rip, O - ospf, B - bgp
