For some reason there is a corrupted LFIB entry on one of my PE routers (6509, Sup720-3B, 12.2(33)SXI2) which disrupts normal traffic flow. The output of the sh ip bgp vpnv4 vrf A labels command shows that MP-BGP assigned label 31 to FEC A(vrf A), but when I do a sh mpls forwarding-table labels 31 I can see that label 31 points to some wrong FEC (FEC B) which resides in vrf B. Is there any way I can force the router to reassign labels to all the FECs it has all over again? Some command? I've found this one "clear mpls ldp checkpoint *" but I'm not sure that it's the right command in my case.
