Routing is a very powerful and necessary tool in modern networking. No stranger to routing, Juniper has extended their legendary routing support for enterprise and carrier class routing into their firewall platform. In this chapter, we covered the various aspects of routing in the Juniper firewall platform. Juniper has implemented a very powerful routing design which follows the theme of permitting granularity in their firewalls. It all starts with the capability of using virtual routers to segment the routing configuration within the Juniper routers. From there, you are capable of extending routing with routing protocols such as RIP, OSPF, BGP, and static routing.

In this chapter, we focused not only upon how to implement the protocols such as RIP, OSPF, and BGP, but also the differences between them, as well as their strengths and weaknesses. While RIP might be a good choice for a small network supporting legacy equipment, it would hardly scale for large networks like OSPF. Of course, you must use BGP if you would like to participate in Internet routing between other autonomous systems, but there are many things you should consider before doing so. We also focused on securing your routing infrastructure in this chapter. It seems appropriate to do so in a security device like a firewall, but routing security is something that is often overlooked even in very security-conscious organizations.

Configuring routing protocols in a network can be a difficult task. Juniper recognizes this and has given a lot of thought to providing...
