Hi,

Disabling IPv6 CEF makes the problem disappear:

Rack2R2(config-subif)#no ipv cef
Rack2R2(config)#do sh ipv6 cef
%IPv6 CEF not running
Rack2R2(config)# ipv cef

Rack2R5#pi 2001:148:5:6::1
!!!!!

Rack2R2(config-subif)#ipv cef

Rack2R5#pi 2001:148:5:6::1
!.!.!
Success rate is 60 percent (3/5), round-trip min/avg/max = 8/9/12 ms

Strange, isn't it?

The test above is from another configuration that I did just to check if the problem was or not related to Hub/Spoke. This is the topology:
R5-----(s0/0.235)-R2-(e0/0.26)-----R6
