I've never seen it. It appears to be part of the new local label prefix filter feature of some sort.
ie: 76k-123-3#config t Enter configuration commands, one per line. End with CNTL/Z. 76k-123-3(config)#ip prefix 76k-123-3(config)#ip prefix-list p0 permit 1.1.1.1/32 76k-123-3(config)#ip prefix-list p0 permit 1.1.1.2/32 76k-123-3(config)#end 76k-123-3#config t 76k-123-3(config)#mpls ldp label 76k-123-3(config-ldp-lbl)#allocate ? global Specify global Routing/Forwarding instance 76k-123-3(config-ldp-lbl)#allocate global ? host-routes allocate local label for host routes only prefix-list Specify a prefix list for local label filtering 76k-123-3(config-ldp-lbl)#allocate global prefix-list p0 76k-123-3(config-ldp-lbl)#end 76k-123-3# 76k-123-3#sh ip prefix ip prefix-list p0: 2 entries seq 5 permit 1.1.1.1/32 seq 10 permit 1.1.1.2/32 76k-123-3#config t Enter configuration commands, one per line.

End with CNTL/Z. 76k-123-3(config)#no ip prefix-list p0 76k-123-3(config)#end 76k-123-3#sh ip prefix-list ..... crash It's fixed in 12.0S branch but hasn't been picked up anywhere later.
