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.
