Library /sys$common/syshlp/nclhelp.hlb set, routing, route_propagation  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Support: L2,IP
    Default: No Route Propagation         Value: Set of protocol pairs

    The default route propagation to be performed. The set may include
    the following protocol pairs:

       EGP to IS-IS      IS-IS to RIP
       EGP to RIP        RIP to EGP
       IS-IS to EGP

    If a particular value is not present in the set, routes are not
    propagated between those two protocols in that direction. This
    characteristic is supported only if the routing protocols
    supported characteristic includes either of the EGP or RIP
    routing protocols.
