Making External Route Selection Rules Defined in RFC 1583 Compatible

The selection of an external route from multiple LSAs defined in RFC 2328 is different from the one
defined in RFC 1583. 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.
Follow these steps to make them compatible:
To do...
Enter system view
Enter OSPF view
Make RFC 1583
compatible
To avoid routing loops, it is recommended to configure all the routers to be either compatible or
incompatible with the external route selection rules defined in RFC 1583.
