[j-nsp] ICMPv6 & 6PE network

[snort bsd]

Thanks again. Yes, I missed one end of "family inet6" (core-facing interface). It is working.

The LSP uses lookpback, but the ICMPv6 uses interface.

Is "family mpls" enabled on all interfaces that the LSP traverses? On  
the PE routers, do you have "family inet6" configured on both the CE- 
facing interfaces and the core-facing interfaces? "family inet6" is  
required on the core-facing interfaces in order to process the IPv6  
packets received with MPLS label 2.
