Usage guidelines
RFC 1583 specifies a different method than RFC 2328 for selecting the optimal route to a destination in
another AS. When multiple routes are available to the ASBR, OSPF selects the optimal route by using the
following procedure:
1. Selects the route with the highest preference:
{ If RFC 2328 is compatible with RFC 1583, all these routes have equal preference.
{ If RFC 2328 is not compatible with RFC 1583, the intra-area route in a non-backbone area is
preferred to reduce the burden of the backbone area. The inter-area route and intra-area route
in the backbone area have equal preference.
2. Selects the route with the lower cost if two routes have equal preference.
3. Selects the route with the larger originating area ID if two routes have equal cost.
To avoid routing loops, HP recommends setting identical RFC 1583-compatibility on all routers in a
routing domain.
Examples
# Disable compatibility with RFC 1583.
<Sysname> system-view
[Sysname] ospf 100
[Sysname-ospf-100] undo rfc1583 compatible
router id
Use router id to configure a global router ID.
Use undo router id to restore the default.
