Dear ALL,
I'm setting the MPLS + OSPF network, the CPE are connecting to the two PE router, the CPE can receive the dst address from the two PE router, but i want to force the traffic via the PE router 1(10.1.8.1) , how to do this?

You might be able to use filters to adjust distance on one vs the other imported route - as changing the interface cost will affect both.
Alternatively, deliver both PE's on a separate ports, or if it must remain single port, split it out in VLANs, this way you can adjust the cost of PE2 slightly higher so it always prefers PE1.

i tried to use the filter to adjust distance, but donesnt work. Is there possible to receive two same dst-address split to two route?
our upstream provide said the circuit cant support vlan passthrough and Q-in-Q,
