Merging two different LTMs in a HA Pair - Q's
Hi,
I have two F5 LTMs with different hardware: 1600 and 3600.
Both have the same software: BIG-IP 9.4.8 Build 355.0 Final
The configuration is just slightly different:
3600 is a production device and have different external interface with different external Self IP and VLAN.
The rest of the configuration apart from that single interface is exactly the same.
I would like to make a HA Pair adding the 1600 to production 3600.
Unfortunatelly I have no failover cable so I will have to do it network-based way.
And now the questions :)
1. can I build the HA Pair with different hardware nodes (1600 and 3600 in particular)?
2. what parts of config should definitely be common on both boxes, and which can't?
- as I wrote before, currently the configs are slightly the same apart from one interface
- of course I know I should change currentl IPs for floating and assign new IPs for both internal and external interfaces on both devices
3. what is the best way to do network based FO?
- dedicated port and vlan with unique addressing like 1.1.1.1 - .2 ?
Thanks in advance for your responses
