I needed to create a virtual with pool members to an ltm device. These new ips are no part of any of the networks available on any trunks on the bigip device.
But the two members are still showing on...

NoctilucentThe health checks will have to source from one of the self IP addresses on your LTM. If the pool members are reachable, then your LTM has the proper route to get there. Try running a tcpdump on all interfaces to see where the traffic is sourcing from:
tcpdump -nni 0.0 host poolmemberipaddress
jaked_150553i ran tcpdump as under: tcpdump -i any host i see no packets going through. One thing i noticed is, ping -R shows the first hop as ip on the management interface. But if I do ping -R on other members from other pool that are already working, i don't see any results. But if run a tcpdump on these members that are working, i see packets to and fro.- Cory_50405Does your LTM have a route via a TMM interface (not management network) to your pool members that you aren't seeing traffic to?
- jaked_150553no there is no route. may be iam missing something. if an ip is not part of any subnet supported on the interfaces of a bigip, how do i still make it work and be marked online by the bigip?
- Cory_50405It'll follow the routing table to reach the pool members. If you don't have a route for the network, then it'll follow the default route on the LTM to get there.
