[c-nsp] RIP SOO not working

[selamat pagi]

My understanding of SOO was that if a vrf-if of a PE is configured with SOO
and a route with the same SOO-value is received, this received route will
not be placed into the vrf RIB.
Is this not correct ?

The issue is that a route propagated by CE10(10.10.10.10)  is seen in CE11
even though on both PEs an identical SSO-sitemap is configured.


Topology:
CE10 - (RIP) - PE1  - (MPLS)  - PE 10 - (RIP) CE11

PE1
interface Ethernet4/0
ip vrf forwarding XYZ
ip vrf sitemap RMSOO

PE10
interface Ethernet2/0
ip vrf forwarding A
ip vrf sitemap RMSOO
ip address 1.106.1.6 255.255.255.0

route-map RMSOO permit 10
