HP 6125XLG - Configuring OSPF Exit Overflow Interval; Enabling Compatibility with RFC 1583; Logging Neighbor State Changes

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:
Ste
p
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. Configure the OSPF exit
overflow interval.
lsdb-overflow-interval interval
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.
