If I need to speak BGP with a customer that only has 1G I will simply make a MPLS L2VPN to one of my edge routers. We use the ZTE 5952E switch with 48x 1G plus 4x 10G for the L2VPN end point. If that is not enough the ZTE 8900 platform will provide a ton of ports that can do MPLS.
I wonder if you'd do this, if you could do L3 to the edge. And why is termination technology dependant on termination rate?
The tunnel is automatically redundant and will promote link down events, so there is not really any downside to doing it this way on low bandwidth peers.
When you say redundant, do you mean that label can take any path between access port and termination IRB/BVI? Or do you actually have termination redundancy? If you don't have termination redundancy, you have two SPOF, access port and termination. If you do have termination redundancy, you're spending control-plane resource from two devices, doubling your control-plane scale/cost. I'm not saying it's bad solution, I know lot of people do it. But I think people only do it, because L3 at port isn't offered by vendors at lower rates. -- ++ytti
