Junos Gives Different Protocols a Clearing House to Work Out Their Differences
Imagine you had RIP running and wanted to configure redistribution from RIP over to OSPF. If you were using a routing platform vendor other than Junos, you might find a way for RIP to interact with OSPF directly so that one can instruct the others’ processes directly. But not so with a Juniper device.
When working in a Junos OS environment, the routing protocols don’t actually have much direct interaction with one another. Rather than have the protocols sort their redistributions on their own, Junos has special unicast routing tables that act as central gathering points where the protocols install their routing information.
This might seem like a subtle difference without much significance, but it’s important to understanding routing decisions in enterprise networks. The protocols use those tables to calculate routes to all destinations and those are placed in a forwarding table and can be advertised to neighbors. Configuring these routing policies can be complicated, but provides a different level of control over interactions between different protocols.
