This article describes how to establish communication between NetScaler admin partition IPs when using shared VLAN.

Instructions

For the Shared VLAN functionality to work properly, in order to establish the communication between the NetScaler Admin Partitions, a following solution can be used.

Partitions can communicate with each other if static host routes are configured. That is, a packet destined from Partition1 to Partition2 must go out of NetScaler to a routing device (Gateway) and then be routed back to same NetScaler on Partition2 VLAN.

For the above scenario, the following set of routes must be added:

A static route to Partition2 needs to be added on Partition1:

> switch partition Partition1
 Done
Partition1> add route 192.168.0.12 255.255.255.255 192.168.0.1

A static route to Partition1 needs to be added on Partition2:

> switch partition Partition2
 Done
Partition2> add route 192.168.0.11 255.255.255.255 192.168.0.1

The routing table for each partition can then be checked using:

show route

After adding the static routes, the partition IPs should have Layer3 connectivity. The packet will be routed through the gateway - it can be determined by decremented TTL (254 for NetScaler).

Using the Shared VLAN feature will allow to use the same VLAN across the partitions.
