Inter-vrf route leaking

I have a set up like this:

SP1 - R3 - SP3 in a simulation i am doing. SP1 and SP3 are acting as PE routers while R3 is P router all running mpls.

I have 2 vrfs on SP1 and SP3: vrf test and vrf customer.

in SP1, i have this: vrf test networks: 10.0.0.0/24 and vrf customer: 192.168.45.0/24

In SP3 , i havethis: vrf test networks: 10.10.10.0/24 and vrf customer: 192.168.12.0/24

In SP1 I have imported 192.168.45.0/24 from customer vrf to test vrf. I can see this imported route on the test vrf table of SP1.

However, i cannot see it in the test vrf table of SP3. I expected that once it is on SP1 test vrf table, it will be seen on test vrf table on SP3.

Is this the normal behaviour or am missing something in my configurations.

Kind regards,

Paul.
