D.2.5.1 Automatic address configuration malfunctions while using standby interface in NIC switching mode

Phenomenon:

If IPv6 virtual interface for NIC switching mode is used on the system operating as an IPv6 router, automatic stateless address configuration in the corresponding network ceases to function after switching the interface in the node. As a result, it cannot hold a communication with site-local/global address.

Cause and how to deal with:

In order to use IPv6 virtual interface for NIC switching mode in the system operating as an IPv6 router, both operation and standby NIC must contain the same configuration information in /etc/inet/ndpd.conf configuration file.

The following is an example of /etcinet/ndpd.conf under situation in which operation NIC is hme1, standby NIC is hme2, and distributed network prefix is fec0:1::0/64.

ifdefault AdvSendAdvertisements true  # Every interface sends a router advertisement.
prefix fec0:1::0/64 hme0              # hme0 sends Prefix "fec0:1::0/64".
prefix fec0:2::0/64 hme1              # hme1 sends Prefix "fec0:2::0/64".
