The purpose of LSAs (Location Service Advertisements) is to inform nearby routers about a new router being introduced to the network, and to exchange routing information among routers using OSPF (Open Shortest Path First) protocol. LSAs help routers build a consistent and up-to-date view of the network topology.

its a network simulation tool .instead of real routers you can use this for example 1 router---spirent device(using this device we can simulate any number of routes,any protocol )
A voice over internet protocol (VoIP) router is a device that is used to connect a computer to the internet or another network. These routers specifically are used to allow users to communicate verbally between two computers, bypassing a traditional phone line and instead using the internet to connect the speakers.
If I remember correctly, wireless routers use the 2.4 frequency, so go with a phone that uses 5.8 and above.

Cisco routers using IGRP (Interior Gateway Routing Protocol) send periodic routing updates every 90 seconds by default. These updates are used to maintain the routing tables and ensure that all routers have consistent routing information. Additionally, IGRP can send triggered updates immediately in response to changes in the network topology to minimize convergence time.
If your router or routers are using Routing Information Protocol version 1 (RIPv1), the RIP Listener service can be turned on to listen for updates sent by the router(s). It will add the new routes to the routing table on the local machine.
https does not 'become' a secure protocol, it 'is' a secure protocol. however, it is 'common practice to intially use the http protocol and 'switch to' or 'use' the https protocol for 'secure' or 'encrypted' communication. information exchanged using the http protocol is exchanged in the 'clear' or using 'plain' text while information exchanged using the https protocol is 'encrypted' (using any number of encryption and or signing mechanisms)prior to exchange. https is an industry agreed upon standard that references the 'secure exchange' of http information.
Some routers have a page that shows devices that are connected, but not who is using the devices.
