Standard Policy-Based Routing with Failover
This example will show how to route packets, using an administrator defined policy. The policy for this setup is the following: route packets from the network 192.168.0.0/24, using gateway 10.0.0.1, and packets from network 192.168.1.0/24, using gateway 10.0.0.2. If GW_1 does not respond to pings, use GW_Backup for network 192.168.0.0/24, if GW_2 does not respond to pings, use GW_Backup also for network 192.168.1.0/24 instead of GW_2.

The setup:



Configuration of the IP addresses:

[admin@PB-Router] ip address> print
Flags: X - disabled, I - invalid, D - dynamic
# ADDRESS NETWORK BROADCAST INTERFACE
0 192.168.0.1/24 192.168.0.0 192.168.0.255 Local1
1 192.168.1.1/24 192.168.1.0 192.168.1.255 Local2
2 10.0.0.7/24 10.0.0.0 10.0.0.255 Public
[admin@PB-Router] ip address>
To achieve the described result, follow these configuration steps:

Mark packets from network 192.168.0.0/24 with a new-routing-mark=net1, and packets from network 192.168.1.0/24 with a new-routing-mark=net2:

[admin@PB-Router] ip firewall mangle> add src-address=192.168.0.0/24 \
\... action=mark-routing new-routing-mark=net1 chain=prerouting
[admin@PB-Router] ip firewall mangle> add src-address=192.168.1.0/24 \
\... action=mark-routing new-routing-mark=net2 chain=prerouting
[admin@PB-Router] ip firewall mangle> print
Flags: X - disabled, I - invalid, D - dynamic
0 chain=prerouting src-address=192.168.0.0/24 action=mark-routing
new-routing-mark=net1

1 chain=prerouting src-address=192.168.1.0/24 action=mark-routing
new-routing-mark=net2
[admin@PB-Router] ip firewall mangle>
Route packets from network 192.168.0.0/24 to gateway GW_1 (10.0.0.2), packets from network 192.168.1.0/24 to gateway GW_2 (10.0.0.3), using the according packet marks. If GW_1 or GW_2 fails (does not reply to pings), route the respective packets to GW_Main (10.0.0.1):

[admin@PB-Router] ip route> add gateway=10.0.0.2 routing-mark=net1 \
\... check-gateway=ping
[admin@PB-Router] ip route> add gateway=10.0.0.3 routing-mark=net2 \
\... check-gateway=ping
[admin@PB-Router] ip route> add gateway=10.0.0.1
[admin@PB-Router] ip route> print
Flags: X - disabled, A - active, D - dynamic,
C - connect, S - static, r - rip, b - bgp, o - ospf
