RSVP Subnetwork Bandwidth Manager (SBM)

Posted by October 4, 2011 in Quality of Service

Scenario:

You are one of the member of a underground organization with special abilities. Your ability is being able to take the form of an IP packet and work your way through the network with your mind. You want to ensure some of the traffic streams are able to make a reservation in the network to ensure there is enough bandwidth.

Goal:

  • All IP addresses have been preconfigured for you.
  • OSPF has been preconfigure for full connectivity.
  • Configure the link between router Mystique and Beast with a bandwidth of 256Kbps.
  • Enable RSVP on all interfaces in the network. Ensure RSVP can use the highest bandwidth on the link between router Mystique and Beast but a single flow should have a maximum of 96Kbps.
  • Configure router Magneto as the Designated Subnetwork Bandwidth Manager.
  • Configure 512KBps for RSVP flows for network 192.168.123.0 /24.
  • Configure router Magneto so it tells router Xavier and Mystique not to send more than 70Kbyte/sec for non-RSVP traffic.
  • You can test your configuration by making reservations from router Xavier and Magneto.

  2. "Configure 512KBps for RSVP flows for network 192.168.123.0 /24."

    With this are we looking to configure the interfaces on that subnet with the 75% default but 512kbps per flow?

    "You can test your configuration by making reservations from router Xavier and Magneto."

    Can you explain this. I think I have my configuration all setup, just not entirely sure how to test it.

  3. i have exception detection error , can i have any document that explaining how to run this lap please

  6. I don’t have a solution for this lab yet…still on the todo list. There’s an example on the Cisco website however that should help you.

  7. Hello,
    This would be my first contribution to this site for that I have been following and reading his book and doing his labs. I think they are helping me a lot. I think the following will be the most close solution for this lab:
