Prefix on-link verification is being performed on statically
configured prefixes. Since these statically configured prefixes
do not have any associated advertising routers, these prefixes
are treated as unreachable and those prefix routes are deleted
from the routing table. Therefore bypass prefixes that are not
learned from router advertisements during prefix on-link check.
