RE: BFD for long haul circuit

[<adamv0025 () netconsultings com>]

Well luckily we have MEF to set expectations about ones EPL/EVPL/EPLAN/EVPLAN performance. (and formal SLA contracts 
describing every single aspect of the service and its performance).

Anyways, when I was designing these the back in the days when it was cool and demand was high, customers (other 
carriers) were getting MTU9100 (to fit customers MTU9000), the whole CFM & LFM shebang (to the point made earlier in 
the thread that the link should go down on both ends -like it’s the case with a wave) and sub 50ms convergence in case 
something when wrong inside our backbone. 

 

We as a provider got more $$$ from single investment to our wave/fiber, but our customers could enjoy p2p links on par 
with wave for less $.

Fortunately .... very fortunately Mark. 

 

L2VPNs running on someone's IP backbone sold by many as "circuits" has many issues ... stability, MTU blackhols, random 
drops - and that is pretty much the same all over the world :( 

 

Very unfortunate technology just to mux more users and get more $$$ from single investment.

 

Cheers,

Thanks for the update. You have any backhauls, that is running over an L2 xconnect  ? I’m facing issue only on the 
backhaul link over a l2vpn ckt.  


Unfortunately not. All our backbones are either over dark fibre or EoDWDM.
