Enabling compatibility with RFC 1583
RFC 1583 specifies a different method than RFC 2328 for selecting an external route from multiple LSAs
This task enables RFC 2328 to be compatible with RFC 1583 so that the intra-area route in the backbone
area is preferred. If they are not compatible, the intra-area route in a non-backbone area is preferred to
reduce the burden of the backbone area.
To avoid routing loops, H3C recommends configuring all the routers to be either compatible or
incompatible with RFC 1583.
To make them compatible:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter OSPF view.
ospf [ process-id | router-id router-id |
vpn-instance vpn-instance-name ] *
N/A
3. Enable compatibility
with RFC 1583.
rfc1583 compatible
Optional.
Enabled by default.
