[c-nsp] ME3600x L3VPN MPLS problems with 15.3.2S

[Adam Vitkovsky]

Just ran into a similar problem with 15.2(4)S2 and 15.3(1)S -can't even ping
the other end of the link -funny is that bgp session works on the CE-PE ip
addresses. 
So routing vise everything works just fine I just can't pass any data. 

However this problem started only when I enabled ipv6 in addition to the
ipv4 setup. 

Debug ip packets for the CE to PE ping shows that the PE got the icmp and
replied back. 
Though the ACL in OUT direction on the PE side did not catch any outgoing
icmp traffic and neither the CE received any.

I tried to deploy Me3600x as MPLS PE with IOS 15.3.2S and failed. It is a
straight forward MPLS L3VPN configuration with OSPF in the core and static
routes between PE - CE. With 15.3 I was not able to ping even a directly
connected CE IP from another PE (7600) in the network.
I was able however ping IP on ME3600 from the same PE - CE subnet. All
routes and labels seem to be fine on both PEs and P as well. I was able
however ping IP on ME3600 from the same PE - CE subnet. The exact same
configuration on the same switch works fine with 15.2S. Just saved config,
rebooted with 15.2 and the ping to the CE direct IP and statically routed
subnet was fine. I was able to replicate the same behavior using a test
ME3600 connected to MPLS core.

Has anybody seen something like this? I am not able to find any similar bug
in the bug toolkit.
