Hi Erwin,
the first step is to create unicast connectivity to the remote servers. That can be a static route:
configure iproute 10.64.23.0/24 10.74.23.254Routes to your IP networks need to be present on the client's router(s) for return traffic.
You might want to redistribute the static route into OSPF:
enable ospf export static cost 10 type ase-type-2Then you need to change the PIM in VLAN OR0 (transit VLAN to the client's router) from passive to active:
configure pim del vlan "OR0" configure pim add vlan "OR0" sparseYou should not need to adjust your RP list, unless the multicast groups using your RP have changed.
HTH,
Erik
