Enabling compatibility with RFC 1583

RFC 1583 specifies a different method than RFC 2328 for selecting an external route from multiple LSAs. If RFC 1583 is made compatible with RFC 2328, the routes in the backbone area are preferred; if not, the routes in the non-backbone area are preferred to reduce the burden of the backbone area.

To avoid routing loops, Hewlett Packard Enterprise recommends configuring all the routers to be either compatible or incompatible with RFC 1583.

To make them compatible:
