All the Cisco documentation I have seen shows RPRs implemented over 15454s physical ring topologies.
Would anyone know whether it is possible to run a Resilient Packet Ring between 15454s where the interconnection between nodes is over a third party SDH network. The physical topology of the 3rd party network is unknown.
yes, it should be possible. RPR needs a ring topology. The transport between two RPR ethernet cards (ML cards) is possible over any SDH network. Normally you would connect the 15454 nodes over STM-16/64 togehther, but you can connect the 15454 SDH interfaces to a third party SDH network. You need only for example a VC4-8c path through the 3rd party network.
It would be good, if the 3rd party network can tunnel the Cisco ONS management protocol, so you have end to end management of the 15454 nodes.
I hope this helps. Please rate all posts.
