Changing network configuration "Allow Administration" on one node, the default route setting vanishes on other node. It causes loads of network problem including imapd, ldap, httpd.

Before changing the network config on one node, other node config is as follows:

Appliance:> configuration net routing show
Properties:
multihoming = loose

Routes:

ROUTE     DESTINATION      GATEWAY          INTERFACE    TYPE
route-000 0.0.0.0/0        134.178.144.238   ipmp2      static
route-001 134.178.144.224  134.178.144.227   ipmp2      system
route-002 134.178.144.224  134.178.144.225   nxge251000 system
route-003 134.178.144.224  134.178.144.226   nxge251001 system
route-004 172.16.0.0       172.16.151.250    nge1       system
route-005 172.16.151.0     172.16.151.16     nge1       system


But after changing, the default route is lost.

Appliance:> configuration net routing show
Properties:
multihoming = loose

Routes:

ROUTE     DESTINATION      GATEWAY          INTERFACE    TYPE
route-000 134.178.144.224  134.178.144.227   ipmp2      system
route-001 134.178.144.224  134.178.144.225   nxge251000 system
route-002 134.178.144.224  134.178.144.226   nxge251001 system
route-003 172.16.0.0       172.16.151.250    nge1       system
route-004 172.16.151.0     172.16.151.16     nge1       system
