[nsp] Ipv6 uRPF with RBE

[Colin Whittaker]

I tought Id through this one out to the list and see if anyone had any
thoughts.

I have a 7200 running 12.3(7)T Enterprise feature set terminating some 
DSL circuits using ATM Route-Bridge Encapsulation (RBE).

The interface config looks like:
!
interface ATM1/0.62 point-to-point
 description "DSL"
 ip address 193.1.196.109 255.255.255.252
 ip verify unicast source reachable-via rx allow-self-ping
 atm route-bridged ip
 atm route-bridged ipv6
 ipv6 address 2001:770:B4::1/64
 ipv6 enable
 pvc DSL 8/62
  ubr 1000
  oam-pvc manage
  encapsulation aal5snap
 !
end

In this state it works fine but if i add the following line:
 ipv6 verify unicast reverse-path
the end stations still recieve router advertisements and can ping the link 
local address of the 7200 but can't ping  2001:770:B4::1 nor anything
beyond the router.

I tried doing "debug ipv6 packet" but the incoming packets are not
logged.
