Route Redistribution Overview

Learn about route redistribution on a firewall.
Route redistribution on the firewall is the process of making routes that the firewall learned from one routing protocol (or a static or connected route) available to a different routing protocol, thereby increasing accessibility of network traffic. Without route redistribution, a router or virtual router advertises and shares routes only with other routers that run the same routing protocol. You can redistribute IPv4 or IPv6 BGP, connected, or static routes into the OSPF RIB and redistribute OSPFv3, connected, or static routes into the BGP RIB.
This means, for example, you can make specific networks that were once available only by manual static route configuration on specific routers available to BGP autonomous systems or OSPF areas. You can also advertise locally connected routes, such as routes to a private lab network, into BGP autonomous systems or OSPF areas.
You might want to give users on your internal OSPFv3 network access to BGP so they can access devices on the internet. In this case you would redistribute BGP routes into the OSPFv3 RIB.
Conversely, you might want to give your external users access to some parts of your internal network, so you make internal OSPFv3 networks available through BGP by redistributing OSPFv3 routes into the BGP RIB.
To Configure Route Redistribution, begin by creating a redistribution profile.
