Symptoms: If redistribution into ISO-IGRP is configured, a crash may occur if the router
configuration is then nv-gened.
configuration is then nv-gened.
Conditions: This symptom is observed when redistribution into ISO-IGRP is configured.
Workaround: If you do not redistribute into ISO-IGRP the bug will not occur. Deconfiguring such
distribution means the bug will not occur. Deconfiguring before nv-genning the router’s
configuration will mean that the bug does not occur.
