I can not configure the RSVP between Cisco6509 SUP2T and Juniper MX480. Prior to that set up the neighbor 3 without problems. Now that it is impossible ...I do not understand why :(

scheme: Cisco t5/5 trunk > Extreme670> Juniper MX480.

side MX

admin@M10_MX480> show configuration interfaces xe-1/0/2.29 
vlan-id 29;
family inet {
    address 185.13.115.89/31;
}
family mpls;

{master}
admin@M10_MX480> show configuration protocols | display set | match xe-1/0/2.29 
set protocols rsvp interface xe-1/0/2.29

  • Do those other RSVP relationships take the same path (through a trunk over a VLAN)?

  • all over SVI ( vlan)

    Do you have traffic engineering extensions turned on in the ospf config on the MX480? set protocols ospf traffic-engineering shortcuts Also: set protocols mpls traffic-engineering mpls-forwarding Juniper is a lot stricter on prerequisite config than Cisco.

From Junos MPLS and VPNs Student GUide Volume 1 of 3 revision 12.a

Basic functional RSVP configuration requires:

1.Adding the mpls family to desired interfaces (not needed for lo0)

2.Linking interfaces with the routers MPLS process

3.Enabling RSVP on desired interfaces

4.Configure the label-switched-path under the protocols mpls hierarchy

As your outputs fall short, and the config given was displayed set|match I can only say based on the evidence you have provided that you are missing point 4. One common mistake I would add is also not having configured no-cspf under mpls stanza.`
