Hello, I have a issue about LSP transit for RSVP protocol on Juniper and Huawei devices.
I`d like to start a RSVP tunnel through Huawei1 --> Huawei2 --> Juniper --> Huawei3. Tunnel is not estabishing, beacuse Juniper blocks create LSP to directly connected Huawei.
Everything works when I create tunnel through Huawei1 --> Huawei2 or Huawei1 --> Juniper. Juniper MX104 works correctly as Ingress or Ergress,
but not works as a transit device.Juniper does not have any entries in the mpls.0 table (which serves as a transit table) for RSVP (LSP paths, of course, work flawlessly)
What could be wrong?What was done:1.
family mpls enabled on interfaces directly connected to others Huawei switches
2. Interfaces above added to
protocol RSVP3. Interfaces above added to
protocol mpls. I create some test tunnels (as ingress works correctly - LSP works)
4. traffic-engineering is enabled, in future I`d like to use fast-reroute.

1. RSVP sessions are UP - when Juniper works as Ingress
2. Neighborship with Huawei is established - my question: neighborship was established only on ip addresses of connected interfaces (on loopback interfaces there is an IDLE status) - I think it`s correct state, because on ip address of connected interfaces routers "speak" together, am I right?
