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
