Configuring OSPF exit overflow interval When the number of LSAs in the LSDB exceeds the upper limit, the LSDB is in an overflow state. To save resources, OSPF does not receive any external LSAs and deletes the external LSAs generated by itself when in this state. Perform this task to configure the interval that OSPF exits overflow state. To configure the OSPF exit overflow interval: Step 1. Enter system view. 2. Enter OSPF view. 3. Configure the OSPF exit overflow interval. Command system-view ospf [ process-id | router-id router-id | vpn-instance vpn-instance-name ] * lsdb-overflow-interval interval Remarks N/A N/A The default setting is 300 seconds. The value of 0 indicates that OSPF does not exit overflow state. 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, HP recommends enabling or disabling RFC 1583-compatibility on all routers in a routing domain. To enable compatibility with RFC 1583: Step 1. Enter system view. 2. Enter OSPF view. 3. Enable compatibility with RFC 1583. Command system-view ospf [ process-id | router-id router-id | vpn-instance vpn-instance-name ] * rfc1583 compatible Remarks N/A N/A By default, this feature is enabled. Logging neighbor state changes Perform this task to enable output of log information to the terminal upon neighbor state changes. To enable the logging of neighbor state changes: Step 1. Enter system view. Command system-view Remarks N/A 73
