Metro Ethernet is typically a point to point or a point to multipoint connection so redundancy becomes an issue if the host site is lost. Metro Ethernet does not typically provide SIP options, so keep that in mind if you want dialtone delivered over Ethernet at your locations.
“Plain old Ethernet” from a service provider is typically a Metro Ethernet offering. Meaning that Ethernet is used to connect two or more locations in one metropolitan area, while MPLS is typically used to connect both metro locations as well as wide area (WAN) locations. Some Metro Ethernet offering can support QoS across their backbone and some cannot. Check with your provider to see if they have this option.
First thanks for the video – I am new to mpls.
However, I keep hearing that (as you mentioned to jsealey762) a major advantage of mpls is that it allows QOS. If the SP is not running mpls, they might be running plain old ethernet (most likely with 802.1q vlans) – this does allow qos (via diffserv and 802.1p). Most hardware (eth devices) vendors also allow redundancy (eaps, rep, rrpp, epsr). So my question – given that you have hardware which support rings on ethernet, are there any adv of mpls ?
@jsealey762 – The biggest benefit to a service provider is the ability to classify traffic. Once the SP has this capability they can set up different classes of traffic to provide different service level agreements (SLAs). SLAs can then be sold to a customer based upon their current needs. For example, voice and interactive video traffic both need priority while email traffic typically does not. So the SP can now customer how much of the link (if any) will receive SLAs for each customer.
I’ve been trying to understand the benefits of MPLS and why it is becoming more common for ISP’s to switch from the original BGP backbone to the MPLS backbone. Attempting to understand the benefits it would provide to an ISP, the best I can come up with is that it allows QoS to be available over the WAN connection.
My question to you is, what other benefits are there for an ISP to use MPLS over BGP?
@davekrunal46 Providers typically use BGP to associate IP addresses with labels. In this way a provider will know which location to switch the packet to reach the destination.
Hope that helps.

How provider edge router determines destination address? I mean, as MPLS doesn’t really examining the packet. It just see the labels so how it will come to know where exactly it needs to send (destination address)?

nice one man very helpful , please is it possible for you to show us how to configure MPLS network ….simulating on GNS3.
thanks in advance
cheers!!!
