MPLS FRR Looping ISSUE.

Ref INE VOD.

Hi,

I have buildup beneath setup on my dyanmips to do MPLS FRR practise.

A-E ,A-B,B-C,C-F,F-E,B-E.

tunnel CA on Router C  using dynamic following path C-B-A

Router C :

  1. int tunnel CA
  2. ip unnun lo0
  3. tunnel destination A.A.A.A
  4. tunnel mode mpls traffic-eng
  5. tunnel-mode traffic-eng path-option 10 dynamic
  6. tunnel-mode traffic-eng fast-reroute

frr on router B --- patch B-E-A .

Router B:

  1. int tunnel BA
  2. ip unnumbered lo0
  3. tunnel destination A.A.A.A
  4. tunnel mode mpls traffic-eng
  5. tunnel mpls traffic-eng path-option ------- path option is B-E-A

     E        F

A       B       C

The problem is when i am testing the MPLS FRR initially traffice is flowing C-B-E-A but later it's following C-B-C-F-B-E-A

In other words i can see some looping .
