Hi all wonder if there's any difference between the advertise filers in RouterOSv6 and RouterOSv7, so far our scenario includes several CPEs running on v6 connected back to a couple of big routers (CCR1072 running v6), everything works as expected, all of our CPEs have some MPLS advertise-filter rules, but there's a small percentage 5% that those filters are not accurate (we catch them roughly, so they're not properly identified), we're talking about >1K routers.
Our goal is to upgrade those 1072 to CCR2216 running v7, our first try was unsuccessful, because for some reason those labels that were filtered in the advertise-filter on each CPE are now taking effect in the 2216, so there's no label for that prefix until that advertise-filter rule is properly set to send that label across the path.
Some show commands: (at the CCR2216 with v7)
[admin@ccr2216] > mpls ldp remote-mapping/print where dst-address=192.168.64.0/30
Flags: I - INACTIVE; D - DYNAMIC
Columns: VRF, DST-ADDRESS, LABEL, PEER
# VRF DST-ADDRESS LABEL PEER
29 ID main 192.168.64.0/30 35 x.x.x.2:0. (that peer is the P router acting as core)
[system@Conc-X-lab] > /mpls ldp neigh print detail
[admin@ccr2216] > /mpls ldp neigh print detail
Flags: X - disabled, D - dynamic, I - inactive;
O - operational, C - active-connect, W - passive-wait, T - throttled;
t - sending-targeted-hello; v - vpls; p - passive; d - on-demand
0 DO p transport=x.x.x.120 peer=x.x.x.120:0 local-transport=x.x.y.19
addresses=x.x.x.120,x.x.y.120,w.w.w.9,192.168.64.1
path-vector-limit=0 on-demand=no used-afi=ip
Some show commands: (at the CPE with v6)
/mpls ldp advertise-filter
add prefix=x.x.x.120/32
add prefix=x.x.y.120/32
add prefix=w.w.w.w.8/30
add advertise=no

When adding the command to the CPE -> /mpls ldp advertise-filter add prefix=192.168.64.0/30 & restarting the LDP neighbors, this is the result:
[admin@ccr2216] > mpls ldp remote-mapping/print where dst-address=192.168.64.0/30
Flags: I - INACTIVE; D - DYNAMIC
Columns: VRF, DST-ADDRESS, NEXTHOP, LABEL, PEER
# VRF DST-ADDRESS NEXTHOP LABEL PEER
29 ID main 192.168.64.0/30 35 x.x.x.2:0 . (that peer is the P router acting as core)
37 D main 192.168.64.0/30 x.x.x.9 impl-null x.x.x.120:0. (that's the CPE)
