Hello,
I am working now on a MPLS/VPN implementation but before I start working on the real thing, I made a test lab implementation.
Everything was OK on the test lab, so I start working on the real network. Everything is OK, I have made three VPNs and it is working OK, BUT I have a difference between the test lab implementation, here is the issue:
TEST LAB:
On the CE-Router when I use the traceroute I got the following output:
A1#trace 203.1.3.1
Type escape sequence to abort.
Tracing the route to 203.1.3.1
1 150.1.31.1 [AS 3] 28 msec 28 msec 28 msec
2 192.168.3.21 [MPLS: Labels 22/28 Exp 5] 484 msec 396 msec 400 msec
3 192.168.3.17 [MPLS: Labels 19/28 Exp 5] 360 msec 592 msec 496 msec
4 150.1.31.13 [AS 3] [MPLS: Label 28 Exp 5] 232 msec 288 msec 248 msec
5 150.1.31.14 [AS 3] 220 msec * 144 msec
REAL NETWORK:
On the CE-Router when I use the traceroute I got the following output:
CE1.GDL#trace 10.2.1.1
Type escape sequence to abort.
Tracing the route to 10.2.1.1
1 10.1.1.1 [AS 14000] 4 msec 4 msec 4 msec
2 200.52.12.227 24 msec 20 msec 24 msec
3 200.52.0.37 96 msec 220 msec 212 msec
4 10.1.1.5 [AS 14000] 16 msec 16 msec 20 ms
5 10.1.1.6 [AS 14000] 20 msec * 20 msec

As you can see on the lab at the CE-Router I could see the MPLS label at the traceroute. BUT at the real network I could not see the Labels.
On neither PE-router is used the "no mpls ip ttl-propagate" command.
Is this due to the IOS version? or could it be anything else?
TIA
Regards!!!
