Hi , I have a network to reach which is 192.168.2.0/24. It is a branch of the company. I have currently added a route to that network via one gateway ( 192.168.0.254) in following way. ip route add 192.168.2.0/24 via 192.168.0.254 Now, We got another gateway which is 192.168.0.250. Now I want to add a route to the same network which is 192.168.2.0/24 via this gateway (192.168.0.250) as well. Then I will have 2 paths to the same network. One path should be primary and the other path should be backup. everything should go via primary path. if the primary path goes down, the backup path should be active. That is the purpose of doing this. Pls let me know whether it is possible or not? if possible, How can I achieve this goal.
One possible solution is to enable one of the routing protocols on your routers, instead of using static routing. For example BGP or OSPF. The routers will than discover which paths to every of the networks you have exist and will dynamically change routing rules (instead of using static set of rules) as the network connections go up and down. In the way you requested in your question. It might be an overkill for simple network. But if your network becomes more complex in the future, you'll have infrastructure to handle it. Another advantage of using standard routing protocol is that they tend to be platform independent. You want to replace that Cisco router with Linux router or Linux router with Cisco router. Guess what, you can use BGP or OSPF on both Linux and Cisco based router and your configuration is not specific to single type of router anymore.
