mpls indirectly peers

[ghtmoha153]

Hello ,,

I have topology like Routers A-B-C, and i need to configure vc from A to C over mpls but i don't need configure it in mpls network . How i can configure that?
thanks

[MHM Cisco World]

first config GRE tunnel and then run MPLS over tunnel 

[ghtmoha153]

what about this command
mpls ldp neighbor 1.1.1.1 targeted ?

[MHM Cisco World]

one Q
B have config MPLS with both A and C?

[ghtmoha153]

No just A and C Configuring with mpls

friend then you need GRE, 

the traffic send label over GRE
GRE run over IP core (i.e. the traffic will not drop in B because it can not read label header) 

[ghtmoha153]

Can you please give me configuration?
