LTM Floating IP`s mac address has gone mad!
Hi there! We have 2 BIG-IP LTM version 9.3.0, I know it s old :) These two have a floating ip between them(HA) and this ip is set on web servers as their default gateway, and it was working fine for a long time, but this week both web servers reported ip conflict and they couldn't ping the floating ip and when we get "arp -a" on web servers they return a wrong mac-address for the floating ip(the mac-address is the address which belongs to BIG-IP s own default gateway which is a cisco ASA), so we changed the web servers default gateway to one of the BIGs self-ip and servers don`t get ip conflict anymore and the "arp -a" returns the BIG-IP mac-address correctly. Is it a known issue on BIG-IP?
VIP IS MARKED GREEN BUT CANNOT BE PINGED, POOL MEMBERS HAVE CONNECTIVITY FROM F5
Hello,Is there any possibility, where a configured VIP on an LTM can be unreachable, even though marked GREEN. The Pool members however can be reached directly. Is there an explanation for this,and how can this be resolved. The Self-Ip is configured correctly,and other VIP in the same VLAN are reachable
Floating IP the same on HA pair?
I am setting up a pair of BIG-IP VE in my lab and following a HA lab guide from F5. The configuration has me setting different floating IPs for each BIG IP. BIG-IP_1 Internal Self IP 10.128.20.240/24 Floating IP 10.128.20.242 External Self IP 10.128.10.240/24 Floating IP 10.128.10.242 BIG-IP_2 Internal Self IP 10.128.20.241/24 Floating IP 10.128.20.243 External Self IP 10.128.10.241/24 Floating IP 10.128.10.243 The load balanced web page comes up fine with either BIG-IP_1 or BIG-IP_2 as Active. My understanding is that the floating IP should be the same on each BIG-IP. However, when I try to give the Floating IP the same address on both BIG-IPs the web page will only display on BIG-IP_1 and times out if BIG-IP_2 is Active. I am confused by this behavior. Can someone explain?
What is the impact of adding a floating IP to an active HA LTM pair?
Hello. I have recently started a new position and while going through the environment I've found a couple pairs of LTMs in HA config with floating IPs for some networks and not for others. I generally follow the best practice of creating a floating IP for any network on any pair of devices. To my knowledge we are not using the LTMs as the default gateway on any of the servers that are load balanced by the F5s. In this case I would think there would be no impact to adding a floating IP and then synching each pair, but since they are production devices I'd like to get some confirmation from the community. Please let me know if you need some more details. Thanks.
