15.2(2)JB

Description (partial)

Symptom:
This bug is identical to CSCud84135. When you upgrade an IOS AP to 15.x train, the connectivity to the default gateway is lost as the command "ip default gateway" does not exist anymore and you have to enter "ip route 0.0.0.0"
However, this requires direct access to the AP as the AP lost all l3 conectivity. This is not acceptable for very large deployments.

Conditions:
upgrade standalone AP to IOS 15.x train
