Description (partial)

Symptoms: After a quick activation/deactivation of a BGP neighbor in the VPNv4
 address family, the router can have a unexpected reload. Traceback shows:

 Conditions: The symptom is observed whenever an old style multicast update is
 received and it uses the same AF value as that for VPNv4. Cisco IOS Release
 12.2(33)XNE has code that detects this behavior, hence the traceback.
