Opened: Apr 13, 2015

Severity: 3-Major

Symptoms

After modifying the BIG-IP system's routing table, traffic for some existing connections might be interrupted because an incorrect route starts being used.

Impact

This might lead to traffic following a different path to the destination and traffic interruption. New connections will work properly, this only affects existing connections.

Conditions

After a routing table modification, routes might be reselected for a portion of connections through the BIG-IP system. When a connection crosses non-strict route-domains, the routing table from a route-domain that is different from the route-domain used during connection start-up may be used.

Workaround

None.

Fix Information

Existing connections now choose the correct route when crossing non-strict route-domains.
