Description

This article describes how to add static route from NetScaler to ZebOS.

Background

Consider the following scenario, there is a static route from the NetScaler to the service provider. User is running OSPF between the NetScaler and the Core switches. User's requirement is to redistribute this static route into OSPF and track the static route to avoid blackhole.

User-added image

LB1 and LB 2 are Citrix NetScalers.
CS01 and CS02 are core switches.


Instructions

Enable monitoring on the static route so that whenever the state of a route in NetScaler packet engine changes it is immediately communicated to ZebOS by NSPPE.

Complete the following steps:

1.To advertise static routes configured on the NetScaler into the OSPF routing domain, run the following command:
enable ns mode sradv

2.Then switch to ZebOS by running the following command on the NetScaler CLI:
vtysh
#conf t
#Config# router ospf
#redistribute kernel
