Why each option
The `show route forwarding-table` command displays the contents of the Packet Forwarding Engine's (PFE) forwarding table, showing the egress interfaces and next-hop information for destination prefixes.
The `show route forwarding-table` command provides information about the routes that are installed in the Packet Forwarding Engine (PFE) and are actively used for forwarding traffic. This output specifically includes the next-hop information, which details the egress interfaces selected for destination prefixes.
`show route table` displays routes in the routing table (RIB) on the Routing Engine (RE), not the forwarding table on the PFE.
`show route table extensive` provides detailed information about routes in the routing table, similar to `show route table`, but does not focus on the PFE's forwarding decisions.
`show pfefwdd` is not a standard Junos OS command for displaying the forwarding table.
