• Question 652:

  An LSP path is configured as follows:

  -Shared-explicit reservation style

  -Make-before-break (MBB) enabled

  -500Mpbs bandwidth reserved on a 1Gbps link

  With 100Mbps of unreserved bandwidth remaining, the operator increases the LSP-path's bandwidth reservation to 900Mbps. What happens to the existing LSP?

  A. CSPF looks for the delta bandwidth, taking down the first path if necessary.

  B. CSPF looks for the delta bandwidth, implementing make-before-break.

  C. After 5 failed attempts to find the bandwidth requested, the head end disables the LSP.

  D. CSPF looks for the entire bandwidth requested, implementing MBB.

  Correct Answer: B
