This memo specifies, for OSPF implementors and users, mechanisms
describing how the protocol operates in ATM networks over PVC and SVC
meshes with the presence of Proxy-PAR. These recommendations require
no protocol changes and allow simpler, more efficient and
cost-effective network designs. It is recommended that OSPF
implementations should be able to support logical interfaces, each
consisting of one or more virtual circuits and used either as numbered
logical point-to-point links (one VC), logical NBMA networks (more
than one VC) or Point-to-MultiPoint networks (more than one VC), where
a solution simulating broadcast interfaces is not appropriate. PAR can
help distribute across the ATM cloud configuration setup and changes
of such interfaces when OSPF capable routers are (re-)configured.
Proxy-PAR can in turn be used to exchange this information between the
ATM cloud and the routers connected to it.

Group of the IETF.
