As a network administrator, it is imperative to know how to interpret the content of an IPv4 and IPv6 routing table. The figure displays an IPv4 routing table entry on R1 for the route to remote network 10.1.1.0.
The entry identifies the following information:
- Route source - Identifies how the route was learned.
- Destination network - Identifies the address of the remote network.
- Administrative distance - Identifies the trustworthiness of the route source. Lower values indicate preferred route source.
- Metric - Identifies the value assigned to reach the remote network. Lower values indicate preferred routes.
- Next-hop - Identifies the IPv4 address of the next router to forward the packet to.
- Route timestamp - Identifies how much time has passed since the route was learned.
- Outgoing interface - Identifies the exit interface to use to forward a packet toward the final destination.
