unless you are using BGP to carry IPv4 (plain old) prefixes, you can
limit label advertisements to your BGP next-hops (which advertise the
vpnv4 prefixes):
no mpls advertise-labels
mpls advertise-labels for PE-loopbacks
!
ip access-list standard PE-loopbacks
permit <address> <wildcard>
strictly speaking you only need to do this on the router where you want
to use VACL, then the adjacent LSRs will pop their label towards this
node..
