retransmission lists to certain neighbours under certain conditions (for example,

in a congested Frame Relay network). In some cases, the number of items in the

list was larger than the number of LSAs in the database.

This issue has been resolved.

Also, a new NRL debugging option has been added to OSPF, to show additions

to and deletions from the neighbour retransmission list. To enable NRL

debugging, use the command:

enable ospf debug=nrl

Note that this option may generate large amounts of debugging output on a

large OSPF network. Use it with care.

To disable NRL debugging, use the command:

disable ospf debug=nrl
