[c-nsp] trace via gre over ipsec tunnel

[vladimir.savostin at eu.effem.com]

Hi, 

We have following network configuration: 
Host1--Router1--(GRE/IPSEC tun)--Router2--(GRE/IPSEC tun)--Router3--Host2 

When doing traceroute from Host1 to Host2 I see the following results: 

Tracing route to Host2 over a maximum of 30 hops 
1 <10 ms 10 ms <10 ms Router1 
2 <20 ms 20 ms <20 ms Host2 

The problem is that tun interfaces don't seen as hop counts. 
There are no some special configuration on tun interfaces. 

May be some of your faced with such problem early? 

Thanks
