How to add 2 IP route from 2 different interfaces to same remote ip

[superman1757]

Hi

I have tried this in other forums but without response.
I have two interfaces, eth0 and eth1 with ip 10.255.1.100 (GW 10.255.1.1) and 10.255.2.200 (GW: 10.255.2.1) subnet mask 255.255.255.0
I want to add failover routing to an IP 192.168.100.100 i.e 1st priority route through GW 10.255.1.1 and second priority route through 10.255.2.1 (i.e primarily reach 192.168.100.100 through eth0 and try through eth1 if eth0 is down or the ip cant be reached from eth0)

is such a route definition possible in IP?

If yes, what would be the commands.
if not, why?

i have an sctp multihoming test to do with (2 IP addresses) in each end point , i want to make 4 paths using the above setup between the two end points.(in the above example, i have provided only 192.168.100.100 for simplicity)

TIA,

Regards,

I am trying to figure out what it is that you want to do here. If I am understanding you correctly you have a system with two paths. You are looking to use one path and if that path fails you want to be about to use the second path. This is advanced routing and you could start HERE and google for linux advance routing.

Hi Robert

Immence thanks for your reply.
Yes, I got redirected to correct info i am looking for.
Will take a look at guide.

So, I reckon that previous to iproute2, the 4 paths for the above scenario would not have been possible.
