   Multiple Routing Tables
   Devices running the Junos OS can accommodate multiple routing tables. The primary routing table, inet.0, stores IPv4
   unicast routes. Additional predefined routing tables exist, such as inet6.0, which the Junos OS creates when the
   configuration requires it. An administrator can create custom routing tables to be used in addition to these routing tables.
   The following is a summary of the common predefined routing tables you might see on a device running the Junos OS:
   •inet.0: Used for IPv4 unicast routes;
   •inet.1: Used for the multicast forwarding cache;
   •inet.2: Used for Multicast Border Gateway Protocol (MBGP) routes to provide reverse path forwarding (RPF) checks;
   •inet.3: Used for MPLS path information;
   •inet.4: Used for Multicast Source Discovery Protocol (MSDP) route entries;
   •inet6.0: Used for IPv6 unicast routes; and
   •mpls.0: Used for MPLS next hops.
