Known Affected Versions:
12.0.0, 12.0.0 HF1, 12.0.0 HF2, 12.0.0 HF3, 12.0.0 HF4

Fixed In:
12.1.0

Opened: Sep 12, 2015
Severity: 1-Blocking

Symptoms

TMM may lose dynamic routing information when failover occurs between either chassis in an HA pair or blades within a chassis. Only TMM is affected: the routing database in ZebOS and tmrouted are not affected. The "tmsh show net route lookup <destination>" must be used to determine if TMM has a route to a particular destination.

Impact

Destinations learned via dynamic routing may not be reachable.

Conditions

Dynamic routing enabled on a chassis.

Workaround

After failover, restart tmrouted with "bigstart restart tmrouted".

Fix Information

Dynamic routing is no longer interrupted upon HA or blade failover on Viprion chassis.
