?Mattias

Thanks for your reply now i have more clear of what it is i am trying to do on 
my lab. What i need is to be able to setup the network now that in the future 
it would support L3 MPLS VPN, and L2 VPN.

Moreover i have this two L3 switch which i confirm do not support MPLS commands 
, with several L2 ones which i want to setup that it is Redundan as well. If 
one PE goes down every thing will still be working 

I hope i am not add confusion to my question.

Cheers.

Maile.

You do not need MPLS to carry the traffic.

But you will offcourse loose all the features MPLS adds to regular data-link 
capabilites.

Hi

Can i do BGP without MPLS between my two PE routers.

My question is to my understabd that BGP carry the means of reachability 
between the two PE but it is the mpls actually carry the traffic. Can someone 
correct me if i am wrong or suggest any best approach to this.

The reason is that my PE router does not support MPLS .

Hope to hear you soon.

Re: [c-nsp] BGP with MPLS

2016-10-04 Thread Nick Cutting 
What you are talking about can only be done on ONE device, at least for L3VPN.  
This is using multiprotocol BGP without VPNV4 bgp - which is fun in a lab, but 
quite useless in the real world.

Jeremy Stretch did a good write-up on this

http://packetlife.net/blog/2010/mar/29/inter-vrf-routing-vrf-lite/

You may need to use vrf lite + physical cables, or a dirty combination of the 
above, but I wouldn't recommend it.

I'm not sure I fully understand you.

You can run multiprotocol BGP between two PEs to exchange routes between them 
however if the PEs don't support MPLS and you are trying to create L2 and/or L3 
VPNs you will be hard pushed to get any traffic flowing :)

Normally MP-BGP would assign an MPLS label value and advertise the prefix and 
label to the neighbouring PE. If your PEs don't support MPLS I guess a label 
might not even be allocated by BGP so they might not even advertise the prefix.


Cheers,
James.

My question is to my understabd that BGP carry the means of reachability 
between the two PE but it is the mpls actually carry the traffic. Can someone

The reason is that my PE router does not support MPLS .
