Step Command 3. Enable the interface to add its MTU into DD packets. ospf mtu-enable Remarks Optional. Not enabled by default. Configuring the maximum number of external LSAs in LSDB Step 1. Enter system view. 2. Enter OSPF view. Command system-view ospf [ process-id | router-id router-id | vpn-instance vpn-instance-name ] * 3. Specify the maximum number of external LSAs in the LSDB. lsdb-overflow-limit number Remarks N/A N/A Optional. Not specified by default. 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.

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.
