81.12.1. How to configure the default IP route in case Abilis is connected to an ADSL USB or V.35/G.703 modem

Enter into the Abilis control-program or open the configuration file with the Console configurator and type the following commands.

a ipr net:0.0.0.0/0 ip:3	Add a default route by configuring in the `IP` parameter the IP resource associated to the WAN connection.
save conf	Save the configuration.

	Note
	In the Console configurator, you must type the command: a sipr id:0 net:0.0.0.0/0 ip:3

81.12.2. How to configure the default IP route in case Abilis is connected to an Ethernet ADSL router

Enter into the Abilis control-program or open the configuration file with the Console configurator and type the following commands.

a ipr net:0.0.0.0/0 gw:192.168.2.254 ip:2	Add a default route by configuring in the `GW` parameter the IP address of the ADSL router and in the `IP` parameter the IP resource connected to the ADSL router.
save conf	Save the configuration.

	Note
	In the Console configurator, you must type the command: a sipr id:0 net:0.0.0.0/0 gw:192.168.2.254 ip:2

81.12.3. How to configure an alternative default IP route

Administrative distance is a feature used by routers to select the best path when there are two or more different routes towards the same destination; the route with the lowest value of AD has the highest priority into the IP Routing table.

In the following scheme, the “Best” route for the network 0.0.0.0/0 is the IP-3 resource. Let's see how to configure the IP-4 resource as the alternative route that will be considered only if the primary one is down; in normal conditions the route towards IP-4 resource is ignored.

	Tip
	Interesting chapter: Section 81.26, “How to use state detection of IP interfaces”.

Enter into the Abilis control-program or open the configuration file with the Console configurator and type the following commands.

a ipad net:0.0.0.0/0 prot:static distance:180 ip:4	Add an entry in the IPAD table for the network 0.0.0.0/0.
a ipr net:0.0.0.0/0 ip:4 -fd	Add an entry in the IPR table for the network 0.0.0.0/0.
save conf	Save the configuration.

On a working Abilis, you must refresh the IPAD table: init ipad.

Note

The option -fd has been used because a static routing towards network 0.0.0.0/0 was already present.
