Description (partial)

Symptom: ISIS IPv6 distribute-list filters of the form:

router isis
 address-family ipv6
  distribute-list prefix-list {name} in {interface}

should be removed from the configuration when the specified interface is deleted or is no longer enabled for IPv6. In some cases this is not happening, which can cause errors when a saved configuration is used during a subsequent reboot.

On systems with a redundant RP, configuration sync will fail because the distribute-list command will be rejected by the standby RP.
Conditions: This symptom is observed when using ISIS to route IPv6 traffic.
