Severity: 3-Major


Neither learned nor default-originate default routes ( are sent to the BGP peer if the BGP peer has terminated the BGP session with TCP FIN, without BGP notify message.


Default routes are not propagated in the network after the BGP peer restart.


1. BGP session is terminated without BGP notify (just TCP FIN). 2. Either learned (not originated in DUT) and default-originate (originated in DUT) routes are not sent.


There is no workaround at this time.

Fix Information

Default routes are now always sent after the BGP session reset. Consistent behavior between BGP session reset with and without BGP notify message.

Behavior Change
