Palo Alto IPV6 configuration for firewalls running in active-active HA

L1 Bithead

Hello All,

 

We have a customer planning to enable IPV6 firewalling in their current  data center firewalls. The firewalls are currently running in active-active HA mode. I have the below queries.

 

1. When I configure IPV6 address on the interfaces, is there any possibility that the HA will break or it will have flaps?.

2. When I configure floating IPV6 addresses on the firewalls, is there any possibility that the HA will break or it will have flaps?.

3. Is it mandatory to configure IPV6 addresses on the HA interfaces (like HA1,HA2 and HA3) ?

 

Kindly advise

Thank you for posting questions @shabeeb

 

We have enabled IPv6 in a few Data Centers and Firewalls are running dual stack. During actual configuration as well as post operation we did not come across any flapping or anything similar related to HA.

 

1. I did not come across this issue and I believe enabling IPv6 on interface is safe and will not cause HA issue.

2. This operation should not cause an issue.

3. It is not mandatory to enabled IPv6 on HA interfaces. Your customer can keep using existing IPv4 HA configuration.

 

Kind Regards

Pavel

Hello Pavel,

So only thing what we need to do is to configure the interfaces, floating IP address field of active-active HA and routing right. In your config you have one floating IP or two IPs?.

To ping to link-local addresses, you MUST specify the name of the output interface (because theoretically the same link-local address can appear behind different physical interfaces.

Thank you for reply @shabeeb  and sorry for late respnse.

 

Yes, this is correct statement: only thing what we need to do is to configure the interfaces, floating IP address field of active-active HA and routing.

Regarding floating IP address, only 1.

 

Kind Regards
