As a carrier I would like to hide certain hops in our network/MPLS ring, e. g. private networks from a customer's traceroute.

Basically, I want to go from

traceroute 50.50.50.2
traceroute to 50.50.50.2, 30 hops max, 60 byte packets
1 30.30.30.1
2 192.168.255.2
3 192.168.255.6
4 192.168.255.10
5 50.50.50.2

to

traceroute 50.50.50.2
traceroute to 50.50.50.2, 30 hops max, 60 byte packets
1 30.30.30.1
2 50.50.50.2

I tried to deactivate the TTL propagation with "undo ttl propagate" and in MPLS "undo ttl propagate public" on the devices, but that did nothing.

To understand what I mean, I have created two graphic files, that may help visualise the scenario.

Does anyone have an idea how to solve this?

    You need to provide more information. For example, what are the router models and configurations? We cannot simply guess. – Ron Maupin Sep 11 at 18:17
  • Actually, we have this scenario twice, once with Cisco MP switches and once with Huawei MP switches like S5300 and S5700. The most important configurations on the switches are shown in the graphic file, saying there is a working routing scenario with MPLS functionality. – vega 14 hours ago
