Error description
Re-create: # netstat -rn Routing tables Destination Gateway Flags Refs Use If Exp Groups default 9.3.131.1 UG 1 1113 en0 - - => # mkwpar -n mywpar -i -I rtdest=default rtgateway=9.3.131.1 # startwpar mywpar # stopwpar mywpar * note: stopwpar triggers the corral/wpar code to eventually call the kernel route component and routine rn_delete Even though WPAR DUP'd route is removed when the WPAR is stopped, it remains DUP'd in the global routing table. The net result, the route is no longer DUP'd, but the global routing table reflects this and all WPARs that use the global routing table will inherit this - one known side-effect is an ICMP redirect that matches the DUP'd route will not be honored [as coded] and a dynamic host will not be created The same problem will manifest when any WPAR DUPs the global default route, than all other WPARs that use the global routing table we'll have a DUP'd default route.
Local fix
Problem summary
ICMP redirects were not honored and a dynamic host route was not added. Global route not cleaned up after identical WPAR route is removed.
Problem conclusion
When identical WPAR route is removed, the global route is cleaned up correctly. This change allows ICMP redirects to be honored and dynamic host route is added.
Temporary fix
