Hello,
It appears you are doing CCC on older HW - what is the exact router model and JUNOS version?
Also, it appears you are doing that in logical-systems because without "vlan-tagging" under physical interface, _BUT_ with "vlan-id" under unit, such config does not commit. Please post the interfaces config from master LS.
Lastly, "encapsulation vlan-ccc" must be repeated on physical interface as well so your complete CCC interface config must look like below. If you are using LS, "encapsulation vlan-ccc" and "vlan-tagging" must be present in master LS under [edit interfaces]:
R2 {
interfaces {
fe-0/3/2 {
encapsulation vlan-ccc;
vlan-tagging;
unit 0 {
encapsulation vlan-ccc;
vlan-id 1102;
family ccc;
}
}
fe-0/3/1 {
encapsulation vlan-ccc;
vlan-tagging;
unit 0 {
encapsulation vlan-ccc;
vlan-id 1102;
family ccc;
}
}
}
HTH
Thanks
Alex
