Unicast Packet
Packet sent to a single destination. The packet is going from one point to another point.

Unicast Routing
Routing method in which a packet is sent to a single host. This differs from multicast
routing in which individual packets are sent to many destinations.

Update Message
Message a router sends to inform its peers of which routes are currently available and
which ones are unfeasible.

User Mode
Mode in which you can monitor the SSR. This mode does not permit you to make
configuration changes (such as changing passwords, configuring bridges or routers, or
setting security filters).

User Datagram Protocol (UDP)
Connectionless protocol in the TCP/IP protocol stack. It performs the same delivery role
as TCP, but does not guarantee delivery.

as TCP, but does not guarantee delivery.
UDP is useful for sending small amounts of data in environments in which you can easily
resend data if delivery fails.
resend data if delivery fails.
Virtual Local Area Network (VLAN)
Devices on different segments of a LAN that are configured to communicate as though
they are on the same wire. VLANs are very flexible because they are logical connections
rather than physical connections.

Waiting
OSPF interface state that indicates the router is trying to determine the identity of the
Backup Designated Router for the network. The router cannot elect neither a Backup
Designated Router nor a Designated Router until it transitions out of Waiting state. This
prevents unnecessary changes of a (Backup) Designated Router.
