Opened: Jun 22, 2014
Severity: 2-Critical

Symptoms

VE is unreachable. - run "ping6 <ve-self-ip>" and no response - run "ip -6 neigh show" and network discovery failed for VE

Impact

VE is unreachable

Conditions

Found it on Ubuntu-14.x KVM when using macvtap interfaces

Workaround

This is not BIG-IP VE issue, instead, it's the default configuration issue on KVM host. We have two workarounds to fix this issue: 1. Use bridge interface(s) rather than macvtap interface(s) 2. Enable promiscuous mode for macvtap interface(s) and all interfaces they derive from

Fix Information

None
