3. Specify the maximum number
of external LSAs in the LSDB.
lsdb-overflow-limit number
By default, the
maximum number of
external LSAs in the
LSDB is not limited.
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:

1. Enter system view.
system-view N/A
2. Enter OSPF view.
ospf [ process-id | router-id router-id |
vpn-instance vpn-instance-name ] *

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 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:
