JUNOS Software Routing Tables

列出JUNOS內有的Routing Tables：

inet.0

This table stores IPv4 unicast routes. Example is given at the beginning of this post. Here is an example that shows only static routes from table inet.0 (protocol static).

inet.1

Table inet.1 is used for IPv4 multicast routes. This table is also known as multicast forwarding cache and contains pair of (Source, Group).

inet.2

Table contains IPv4 unicast routes used by multicast for RPF (Reverse Path Forwarding) to prevent routing loops.

inet.3

Routing table inet.3 contains egress IP address of a MPLS label switched path (LSP).

inet.4

This routing table stores information learned using the Multicast Source Discovery Protocol (MSDP).

inet6.0

This table is used by IPv6 routes (see that change? It is inet6 now). After dot we have number 0, which means that it is used once again for unicast routes.

mpls.0

As name implies, routing table is used by MPLS. Better name is switching name.

bgp.l3vpn.0
