- Segmenting a large network to smaller VLANs is cheaper than creating a routed network with routers.

- A malicious user can't just plug his/her laptop into any switch port and sniff the network traffic using a packet sniffer. The network administrator controls each port and whatever resources it is allowed to use.]]> 2017-03-18 17:38:28 UTC https://padlet.com/lorenzo_giglio/u3hp8r86jl0h/wish/160945130 lorenzo_giglio https://padlet.com/lorenzo_giglio/u3hp8r86jl0h/wish/160945519 While traditional InterVLAN routing requires as many interfaces as the VLANs we're working with, a router on a stick is a router that has a single connection to the network and is used to forward traffic between hosts that are in different VLANs.]]> 2017-03-18 17:46:13 UTC https://padlet.com/lorenzo_giglio/u3hp8r86jl0h/wish/160945519 lorenzo_giglio https://padlet.com/lorenzo_giglio/u3hp8r86jl0h/wish/160946708 2017-03-18 18:07:28 UTC https://padlet.com/lorenzo_giglio/u3hp8r86jl0h/wish/160946708 lorenzo_giglio https://padlet.com/lorenzo_giglio/u3hp8r86jl0h/wish/160946759 When using VLANs to segment a network, the only way to make two hosts from different VLANs communicate is by using a router (or layer 3 switch) to route packets between VLANs.]]> 2017-03-18 18:08:26 UTC https://padlet.com/lorenzo_giglio/u3hp8r86jl0h/wish/160946759 lorenzo_giglio https://padlet.com/lorenzo_giglio/u3hp8r86jl0h/wish/160947014 2017-03-18 18:12:28 UTC https://padlet.com/lorenzo_giglio/u3hp8r86jl0h/wish/160947014 lorenzo_giglio https://padlet.com/lorenzo_giglio/u3hp8r86jl0h/wish/160955478 2017-03-18 21:35:19 UTC https://padlet.com/lorenzo_giglio/u3hp8r86jl0h/wish/160955478 lorenzo_giglio https://padlet.com/lorenzo_giglio/u3hp8r86jl0h/wish/160956875 2017-03-18 22:18:52 UTC https://padlet.com/lorenzo_giglio/u3hp8r86jl0h/wish/160956875 lorenzo_giglio https://padlet.com/lorenzo_giglio/u3hp8r86jl0h/wish/160956948 Website
