Routing Protocol Process

The JUNOS software routing protocol process controls the routing protocols that run
on the router. The routing protocol process starts all configured routing protocols
and handles all routing messages. It consolidates the routing information learned
from all routing protocols into common routing tables. From this routing information,
the routing protocol process determines the active routes to network destinations
and installs these routes into the Routing Engine's forwarding table. Finally, the
routing protocol process implements the routing policies you specify, which determine
how routing information is transferred between the routing protocols and the routing
table.
This section discusses the following topics:
For complete information about routing concepts, see the JUNOS Internet software
configuration guides.

IPv4 Routing Protocols

The JUNOS Internet software implements full IP routing functionality, providing
support for IP version 4 (IPv4). The routing protocols are fully interoperable with
existing IP routing protocols and provide the scale and control necessary for the
Internet core. The software provides support for the following routing and traffic
engineering protocols:
