Symptoms
The advertised next-hop is a floating-IP of the active traffic-group on a peer BIG-IP system, although it should be the floating-IP of the traffic-group active on the current BIG-IP system.
Impact
An incorrect next-hop in BGP is advertised for a traffic group in Active-Active deployment. Traffic for relevant advertised routes might go to a standby device.
Conditions
-- In a BIG-IP high availability (HA) configuration.
-- The HA configuration is Active-Active topology.
-- There are multiple traffic-groups, in which each device is active for one traffic-group.
Workaround
Configure the floating address of a traffic group as the next-hop in its route-map.
Fix Information
The advertised next-hop in BGP is now the smallest floating-IP active on the current BIG-IP system. Note: The ZebOS routing protocol suite available for BIG-IP configurations does not support traffic groups, so this issue might still be seen in certain circumstances.
