JunOS routing table(s)

JunOS has a bulk of different tables for building the global routing table.
I was searching several times for informations what table holds which routes, because i can’t keep it in mind.
Therefore i decided to write it down in my blog…

Here comes the summary (taken from Juniper website)

Table Purpose
bgp.isovpn.0 Border Gateway Protocol (BGP) reachability information for ISO virtual private networks (VPNs).
bgp.l2vpn.0 BGP Layer 2 VPN routes.
bgp.l3vpn.0 BGP Layer 3 VPN routes.
bgp.rtarget.0 BGP route target information.
inet.0 Internet Protocol version 4 (IPv4) unicast routes  (–> main IP routing table)
inet.1 IP multicast routes. Each (S,G) pair in the network is placed into this table.
inet.2 IPv4 unicast routes. Used by IP multicast-enabled routing protocols to perform Reverse Path Forwarding (RPF).
inet.3 Accessed by BGP to use Multiprotocol Label Switching (MPLS) paths for forwarding traffic (e.g. when using MPLS with traffic-engineering)
inet.4 Routes learned by the Multicast Source Discovery Protocol (MSDP).
inet6.0 Internet Protocol version 6 (IPv6) unicast routes.
inet6.3 Populated when the resolve-vpn statement is enabled.
inetflow.0 Border Gateway Protocol (BGP) flow destination (firewall match criteria) information.
invpnflow.0 BGP flow destination (firewall match criteria) information within an RFC 2547 Layer 3 VPN.
iso.0 Intermediate System-to-Intermediate System (IS-IS) and End System-to-Intermediate System (ES-IS) routes.
l2circuit.0 Layer 2 circuit routes.
mpls.0 MPLS LSPs. Contains a list of the next LSR in each LSP. Used by transit routers to route packets to the next router along an LSP.
instance-name.inet.0 Table that JUNOS software creates each time you configure an IPv4 unicast routing instance.
instance-name.inet.3 Table that JUNOS software creates for each BGP instance that is configured to use MPLS paths for forwarding traffic.
instance-name.inet6.0 Table that JUNOS software creates each time you configure an IPv6 unicast routing instance.
instance-name.inetflow.0 Table that JUNOS software creates each time you configure a routing instance. This table stores dynamic filtering information for BGP.
instance-name.iso.0 Table that JUNOS software creates each time you configure an IS-IS or ES-IS instance.
instance-name.mpls.0 Table that JUNOS software creates each time you configure MPLS LSPs.
