Enabling compatibility with RFC 1583
The selection of an external route from multiple LSAs as 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… Use the command… Remarks
Enter system view system-view —
Enter OSPF view
ospf [ process-id | router-id router-id |
vpn-instance vpn-instance-name ] *

Enabled by default
NOTE:
To avoid routing loops, H3C recommends configuring all the routers to be either compatible or
incompatible with RFC 1583.
