Next-hop IP address:

For a static route to be added to the routing table, the next-hop IP address must be reachable. If it is not reachable, the route cannot be considered valid and will not be added.

Interface status:

If the interface specified in the static route configuration is down, the route will not be added to the routing table. The interface must be up and operational for the route to be valid.

Priority and Distance:

While priority and administrative distance affect route selection, they do not prevent a route from being added to the routing table. Instead, they influence which route is preferred when multiple routes to the same destination exist.

Kernel Slabs Overview:

The slab allocator in the Linux kernel is used for efficient memory management. It groups objects of the same type into caches, which are divided into slabs.

Each slab contains multiple objects and helps to minimize fragmentation and enhance memory allocation efficiency.

Interpreting the Exhibit:

The exhibit shows output related to various kernel slab caches.

The line forip6_sessionindicates that there are 1300 kB allocated for this slab, which means the total memory size allocated for IPv6 session objects in the kernel is 1300 kB.

Session Table Overview:

The session table in FortiOS tracks all active and pending sessions. It includes details like the type of session (TCP, UDP, etc.), status, and statistics.

Interpreting the Exhibit:

The exhibit from thediagnose sys session statcommand shows detailed session statistics.

The specific value indicating "166 TCP sessions waiting to complete the three-way handshake" reflects the number of sessions that have initiatedbut not yet completed the TCP three-way handshake process (SYN, SYN-ACK, ACK).
