Routing Interview Question:

How to Set a defaultrouter?

Submitted by: Administrator

If you want to define a default router, so that you can send all of your non-local packets through one standard machine, simply create the file /etc/defaultrouter. It should have as its sole contents, the hostname or ipnumber of your router: %%%% cat /etc/defaultrouter router-1 or: 150.101.16.1 Note that any machine listed as a defaultrouter _must_ be on the same subnet as your machine and the name listed in /etc/hosts. On Solaris 2.4, and later, you can actually list multiple routers in the /etc/defaultrouter file, one default router per line: %%%% cat /etc/defaultrouter router-1 router-2 router-3 You also need to make sure that every name which appears in /etc/defaultrouter has an entry in your /etc/hosts file: %%%% cat /etc/hosts ... 150.101.16.1 router-1 150.101.16.2 router-2 150.101.16.3 router-3 After you have created /etc/defaultrouter, and made sure that any names listed in that file are also listed in /etc/hosts, you can reboot your machine. When it comes back up, it will automatically be routing through the defaultrouter that you have defined. If you have a simple network, or if you are just trying to get routing to work after your Sun machine is first installed, you probably want to set up a defaultrouter, as is described here. Some further advice on what type of routing to use. How does multiple default routes work?
