Description

It seems that IPv6 neighbor discovery does not always work for shared-ip non-global zones.

To reproduce:

1) create a zone with ip-type=shared
2) add a previously unused IPv6 address
3) boot the zone
4) try connecting to the new IPv6 address from somewhere behind a router (eg. telnet zone_ipv6_addr 22)

The address will seem unreachable until an IPv6 packet is sent out from the zone, which will cause the router to enter the zone's IPv6 address into its ND cache.

I can reproduce this on two different systems. One is running oi_151a6 and the other is oi_151a7.

The problem does not occur when using ip-type=exclusive.
