Hi All,
  
  I have a basic question in FRTS.
  
  In IEWB Lab 19, I have a hub and spoke topology where R3 acts as Hub and R1 and R2 as Spoke. The question 8.1 says the R3's serial interface is 1536Kbps and asks me to configure 64Kbps CIR for 302 PVC. I am done with this.
  
  The next question asks me to configure the network in a way that the previous question will not affect the network performance. (This involves PVC 301)
  
  From the above 2 question, I assume the PVC 301 should be assigned a CIR value which should be equal to (Line Rate - PVC_302_CIR). But the solution guide seems to have configured with full line rate as CIR for PVC 301. AFAIK, CIR is the guaranteed bandwidth. So based on the solution guide, it seems, we guarantee (1536+64)Kbps on a link with 1536Kbps BW.
  
  Am I missing anything here?. Can some one please clear me.
  
  Regards,
  Nagendra
