A system with IPv6 configured on an e1000g interface might not respond to “Neighbor Solicitation” messages from a remote machine. Consequently, remote machines might not be able to communicate with the target system by using IPv6.
Workaround: Stop and restart the IPv6 interface by using the following steps:
Become superuser.
Shut down the IPv6 interface.
# ifconfig e1000g0 inet6 down |
Restart the IPv6 interface.
# ifconfig e1000g0 inet6 up |
You can now communicate with this target system by using IPv6 from the remote system.
The ifconfig commands shut down and restart the IPv6 interface. You can add these commands to the system's level-3 boot scripts to automate the workaround steps.
If you configure multiple IP tunnels between two IP nodes, and enable ip_strict_dst_multihoming or other IP filters, packet loss might result.
Workaround: Choose one of the following:
First, configure a single tunnel between the two IP nodes. Add addresses to the tunnel by using the ifconfig command with the addif option.
Do not enable ip_strict_dst_multihoming on tunnels between two IP nodes.
