Issue

Intercluster (IC) LIFs lif-A and lif-B are in segregated networks.

nas-cm913::> net int show -role intercluster
  (network interface show)
            Logical    Status     Network            Current       Current Is
Vserver     Interface  Admin/Oper Address/Mask       Node          Port    Home

nas-cm913
            lif-A
                         up/up    172.16.32.201/16   nas-cm913-01  a0a-1   true
            lif-B
                         up/up    192.16.32.202/16   nas-cm913-02  a0d-1   true
2 entries were displayed.

Both IC LIFs are in the same IPspace

nas-cm913::> net int show -role intercluster -fields ipspace
  (network interface show)
vserver   lif             ipspace
--------- --------------- -------
nas-cm913 lif-A           Default
nas-cm913 lif-B           Default
2 entries were displayed.

If lif-A is disabled and lif-B is enabled, the cluster peer relationship is Available

nas-cm913::> net int show -role intercluster -fields status-admin
  (network interface show)
vserver   lif             status-admin
--------- --------------- ------------
nas-cm913 lif-A           down
nas-cm913 lif-B           up
2 entries were displayed.

nas-cm913::> cluster peer show

nas-cm910                 1-80-000011           Available      ok

If both lif-A and lif-B are enabled, the cluster peer relationship is Unavailable

nas-cm913::> net int show -role intercluster -fields status-admin
  (network interface show)
vserver   lif             status-admin
