@chimeranzl9147 9 жыл бұрын

at 7:05, whats the purpose of it swapping the label for a new number? why doesn't it just keep label 17 in this example? or is that new label effectively the identity of the next LSR in the LSP as predetermined by the LDP?

@tejasshah64 6 жыл бұрын

Yes, its the identity of the next LSR in the LSP.

@akindeleadebayo6504 5 жыл бұрын

I think swapping of the labels helps to identify where a packet is coming from, probably within Routers belonging to a single ISP or from routers belonging to several ISPs since the internet cloud is a collection of several ISPs.

what if I add a switch (due to some reason) between LER n LSR would the switch create any congestion?

@johncollinson8382 7 жыл бұрын

As long as the switch is capable of handling the larger frame size there usually shouldn't be a problem.

IT was very informativ, but i think that at 9min 21 seconds PHP happens, beacause LER send label 3. < Very close to last LER, remove label, so he will not do two look up, only IP look up and send normal IP packet> So R4 send label 3 to R3. In case of MPLS VPN, R4 should receive bottom label | vpn label| thx

@johncollinson8382 7 жыл бұрын

Thanks for the comment, which is correct for IP/MPLS. But remember that PHP is not used in MPLS-TP. The video is intended to get across basic principles. PHP, ECMP and Label Merge are not covered here.

@ansonrinesmith 7 жыл бұрын

I thought the last LSR did the pop before going to the LER? Penultimate pop?

@johncollinson8382 7 жыл бұрын

What you describe is PHP (penultimate hop popping) - and indeed this can be a feature of IP/MPLS to reduce the load on the final LER. However, it is not (and must not) be a feature of MPLS-TP to ensure end to end traceability is possible. See my second video on MPLS-TP.

@peternowak7583 8 жыл бұрын

There is no explanation on what the label is used for, just that it is mapped to the original IP address, exchanged, and popped as it goes through the MPLS network... My question, what does the label represent? What is it used for? I'd be guessing that the the label is that of the next hop LSR and that each LSR would need to strip the label, execute a table lookup on the destination IP and then add it's own label for the next hop LSR. How is this quicker with each LSR executing a table lookup? I must be missing something....

@johncollinson8382 8 жыл бұрын

+Peter Nowak The point is that - after all the tunnel paths in the MPLS network are initially set up (by for example LDP in IP/MPLS or configuration in MPLS-TP) - the ongoing switching of traffic packets in any LSR from input port to output port will be very rapid, because the only thing the LSR has to do is look at the incoming label, do a simple table lookup to find out which port to send it out of, and swap the label. That should always be much quicker than the analysis of IP routing tables - which requires a match with the longest prefix before forwarding can take place. LSP labels themselves don't represent anything - they only have local significance. Let's take an example: - in an LSR any packet arriving with label 100 will always be swapped for label 101 and forwarded out of port 2; any packet arriving with label 200 will always be swapped for label 300 and forwarded out of port 5, and so on ... In more complex networks packets can have multiple 'stacked' labels - but even then the process is just as quick because only the topmost label is 'examined' and acted on.

@cowan1130 8 жыл бұрын

+John Collinson thank you. this helped answer the same question.

@akindeleadebayo6504 5 жыл бұрын

Labels also help to identify the source of a packet and where next is to be forwarded (Destination) so quickly without having to start analyzing the header of the packet which can be time consuming. The path of the label is already predetermined.

Thanks for the comment. However Brits (like me) and Europeans pronounce it as "Rooter". The way Americans pronounce it we reserve for a woodworking tool.
