Description (partial)

Symptom:The 'passive-interface default' command under router isis mode may not take effect in a configuration with both ISIS IPv4 and IPv6.  Some interfaces may not be made passive and their prefixes may not be included in the ISIS database.

Depending on the build, ISIS IPv6 registry maybe invoked before IPv4 causing the 'passive-interface default' to behave incorrectly.

Configuration with both ISIS IPv4 and IPv6 maybe affected.
