Description

While upgrading SRX in MNHA using the command "request system software add /var/tmp/<image> " from JUNOS 22.4R2-S2.6 to 23.4R2-S2.1 fails

 


During the upgrade the below error is observed -

<<< trimmed >>>

[edit chassis high-availability services-redundancy-group 1 virtual-ip 1 interface]

'interface ae0.666'

Virtual IP interfaces must be unique

[edit chassis high-availability services-redundancy-group 2 virtual-ip 1 interface]

'interface ae0.666'

Virtual IP interfaces must be unique

<<< trimmed >>>

Symptoms

Software upgrade fails

Solution

The interface ae0.666 is configured with both ipv4 and ipv6 ip-addressed and is used in 2 Redundancy-group virtual-ip <vip name>

 

Support for using multiple VIPs or dual stack is not available in SRX for MNHA

We will see a warning reporting "## Warning: Virtual IP interfaces must be unique" if we configure the same interface under different RG VIP hierarchy.
