I am in the process of writing up a change to delete config from a GTM Sync Group which I am fine with but I am looking to confirm my thoughts on how to restore the configuration should I need to back the change out. For an LTM F5 I would create a UCS file on the Standby device before making any changes as the first step. Then should I need to rollback I would just restore the UCS file to the Standby device, check that the configuration has restored correctly and then sync the Standby device to the Active. I think that a similar approach will work for the devices in the GTM Sync Group but I want to avoid the restored config automatically syncing to the other devices in the GTM Sync Group so my thoughts on how to do this are as follows: 1. Log onto the Standby F5 2. Navigate to DNS > Settings > GSLB > General 3. Untick the 'Synchronize' and 'Synchronize DNS Zone Files' tick boxes 4. Change the Group Name to something unique. 5. Save the config 6. Create the UCS file 7. Reverse the changes made in Steps 3 and 4 8. Delete configuration The thinking here is that should I need to restore the config from the UCS file there is no chance of this automatically syncing to the other devices in the GTM Sync Group since it was not part of the GTM Sync Group when this was taken. Once restored I would then update the description for one of the WideIP's (simply append something like '1234' to it) so that this has the higher 'commit-id' and then add the device back to the GTM Sync Group. Since the newly added device has the highest 'commit-id' this would then push the confog back to the GTM Sync Group and I am back where I started. To my mind this makes sense but it would be very much appreciated if I could get a second opinion on this.Solved199Views1like5Commentsgtm_add failing due to CERT error
I am trying to cluster to GTM devices using the gtm_add command, but this is failing with this error: ERROR: found "END CERT..." without BEGIN at line: 0.

Hello All, Sorry for the basic question, but I find the deployment guides and implementation guides lasking some basic information. When deploying a redundant GTM pair, does the listener for the DNS queries use the floating IP address? When deploying a single GTM it is mentioned that we use a self IP, but for a redundant pair it does eplicitly say. Since the configuration is done on one GTM in the pair and synchronised to the other backup device, I do tno think a self-IP is going work. Can we use a IP from the subnet used for the LTM VIPs? This subnet is not on a directly connected VLAN, but is a subnet that is routed to the BIg-IP. Many thanks, MichaelSolved1.3KViews1like2CommentsGeolocation when LDNS in a different geography than user doing the lookup
I am wondering if anyone has clever thoughts on how to address the situation with Topology load-balancing on F5 DNS. If a user is in EMEA but their ISP DNS server is in the US, it will be that DNS server in the US whose IP is analyzed by the geolocation database on the F5 and the GTM will respond with the DNS entry appropriate for US IP addresses. This circumvents our geolocation intent. Is there anything anyone has come up with to do to address this?627Views1like2CommentsVirtual server address space on disaster recovery F5 instance
I am working on setting up a disaster recovery instance of an existing HA BIGIP pair. I would like to ConfigSync (sync only) my local devices to the new device which is located in a different data center. The issue is that if/when I needed to "fail over" (manually) to the new disaster recovery device, the IP space of the virtual servers are different. So for example if my virtual server "A" has a destination address of 192.168.1.10 in my existing data center, the new destination address might be 10.1.1.10. (Note: I am less worried about pool member IP space, because I can use priority groups and have the disaster recovery pool member IPs pre-configured but disabled). My first thought was a "DR go live" script which would search & replace the config file and reload it, but is there a more "elegant" way to handle this dilemma, without having them have the same IP space?629Views1like1Comment
