Symptoms

When a dynamic routing protocol is in use and a self IP is moved from one VLAN to another, the connected route for the self IP network may be removed from ZebOS and not readded.

Impact

Networks advertised or learned via dynamic routing may not be reachable if they depend on the connected route.

Conditions

Dynamic routing is configured, self IP is moved from one VLAN to another.

Workaround

Restart tmrouted. Note: This interrupts dynamic routing.

Fix Information

Moving self IPs between VLANs no longer leaves dynamic routing in an inconsistent state.
