What routing table is used for IPv6 unicast routes by default?

The routing table used for IPv6 unicast routes by default is indeed the inet6.0 table. This table is specifically designated for handling IPv6 addresses and routes, distinguishing it from inet.0, which is used for IPv4 unicast routes.

When configuring routers, it is essential to understand the separation of routing tables for different IP versions to avoid any potential overlaps or misconfigurations. The inet6.0 table is tailored to manage all aspects of IPv6 routing, including the storage and management of IPv6 prefixes, next-hop information, and various other routing attributes pertinent to the IPv6 protocol.

In contrast, the inet.adj table is utilized for storing adjacency information, while the inet.1 table is often used for secondary or alternative IPv4 routing, thereby reinforcing the distinct role each routing table plays. Mastery of these distinctions is crucial for effectively managing IP routing within Junos OS, ensuring optimal performance and routing fidelity.
