[c-nsp] L2TP tunnel for BGP peering

[Kanagaraj Krishna]

Hi, 
    Due to cost issues tied to direct IPLC, we are thinking of running 
BGP sessions with upstream providers through L2TP tunnels. It would be 
very helpful,  if anyone in the group share advises on the pros and 
cons of this setup. A few other doubts are: 

- We have concerns on the stability of the virtual link like quality 
drop etc. Are there any mechanism to improve this as drop of  tunnel 
would cause BGP flapping/dampening ? 
- What would be the overhead on the bandwidth throughtput? 


We would like to get more input before looking into further. Thanks
