RE: [RPRWG] A question on IP over RPR
This is responsibility of the upper layers. There are several ways this can
be done. One approach would be to recognize each ringlet as a separate
interface. Each interface would then show up as a routable interface and if
the same route is learnt from both these ringlets, the routing protocols
will make a choice based on configured weights, costs and other parameters
to choose "least cost forwarding" interface and installs that route in the
kernel routing table.
The other approach involves exporting only one RPR interface for all the
ringlets to the routing protocols. The decision on how to forward the data
is something that can be done at the RPR MAC client level because the
topology information is present in the MAC.
In other words, either approach is supportable by RPR and the decision
should be left to individual network configurations and the user.

A question of IP over RPR.
According to IP address, using routing protocol, a data forwarding route can
be selected. On the other hand, RPR may transfer data through
its ring on both direction. How can consistency of L3 and L2 data transfer
be guaranteed?
Can someone explian this? Thanks.
