default / static routes on f5 virtual edition

In case of Nodes, blue is correct because you do not need to monitor Nodes. You need to monitor Pool Members. Configure a LTM pool, add a few members to it, and configure a health-check. After the first health-check completes, you will either see the pool members as Green or Red. Blue means the health-check is not configured or that the first cycle of health-check has not completed.

Hello Hannes.

Thanks for your answer. I now configured a pool containing one node. Status is unchanged. Pool /and/ Node remain blue. This is the message i see in the gui.

For pool:

Unknown (Enabled) - The children pool member(s) either don't have service checking enabled, or service check results are not available yet 

and for the node:

Unknown (Enabled) - Node address service checking is enabled, but result is not available yet 2015-11-09 10:40:48 

Health check is ICMP.

In the tmm log i see a lot of:

<13> Nov  9 12:39:56 bigip notice MCP connection expired early in startup; retrying

Thanks for your help so far.

For further troubleshooting, please provide outputs for the three commands below:

tmsh list ltm pool MyPoolName
tmsh show ltm pool MyPoolName
tmsh list ltm node My.No.de.IP

Hello Hannes.

I fixed the problem. Well i obviousely caused it myself by adjusting some arp setting in /etc/sysctl. I switched the settings back to default and now the checks are green. Sorry for the noise.

thank you again. t.

thank you again. t.

Maybe one last question. Where do i put:

ip r add 191.255.255.1 dev eth0
ip r add default via 191.255.255.1

I thought /config/startup would be the right place.

thanks and cheers t.

Hello Hannes.

Well thats what i tried, but:

[root@bigip:Active:Standalone] ~ tmsh create net route default network 0.0.0.0/0 gw 191.255.255.1 01070330:3: Static route gateway 191.255.255.1 is not directly connected via an interface. [root@bigip:Active:Standalone] ~

The F5 virtual has no ip in that network (191.255.255.1). Thats why i have to do a:

ip r add 191.255.255.1 dev eth0 
ip r add default via 191.255.255.1

But thats not reboot safe obviousely. I put those two commands in /config/startup but that only works now and then. Any ideas?

thanks t.

Hello Hannes.

"tmsh create net route default network 0.0.0.0/0 interface VLAN6"

That does not seem to work. I made now a litte shell script which checks if there is that specific route and if not it sets the route. That works good enough for me.

Thanks again for your help t.
