Now, let us conclude this section by talking something about rooters, OK, routers are used to connect
together and to load packets of data from one network to another.
Cisco has become the de facto standard for routers because of its high quality products, great selection
and fantastic service routers by default.
Breakup of broadcast domain.
Now, breaking up a broadcast domain is important because when a host of Kosovo sends a network broadcast,
every device on the network must read and process that broadcast unless you have got Rafto.
So in of the interface receives this broadcast, it can respond by basically saying thanks but no thanks
and discard the broadcast without forwarding it on the networks.
Now, even though routers are known for breaking a broadcast domains by default, it's important to
remember that the break up collision domains as well.
So in short, routers are the devices which break broadcast domains as well as collision domains.
Now, there are a couple of disadvantages and advantages as well.
But first, we'll see advantages without those do not forward broadcast by default or multicast packets.
Now routers use logical address in the network layer header.
Then routers can use access lists to control security on the type of packets.
Routers can provide layer to switching.
We all know that.
So that's it for this lecture in the next lecture in the last election of this election, we will have
a quick recap and summary of what we have seen and learned in this section.
