ALTER SUBNET Command for TCP6MAN

Sending an RA message to ND6HOSTD process. Upon receipt of this
message, ND6HOSTD process becomes responsible for automatically
updating the global address information in DNS.
Specifying this attribute as OFF disables the routing table and interface
configuration update during the RA message processing. The default value is OFF.
IPV6 Examples

To initializes the loopback interface for use with IPv6:
-> ALTER SUBNET LOOP0, FAMILY INET6, IPV6 UP

In this example an ADD SUBNET command first creates an IPv4 SUBNET named
SN1. An ALTER command then enables IPv6 for that SUBNET. Finally, a second
ALTER SUBNET command configures an IPv6 prefix for SUBNET SN1.
-> ADD SUBNET $ZZTCP.*.SN1, TYPE ETHERNET, &
IPADDRESS 172.17.215.232,&
SUBNETMASK 255.255.255.0, DEVICENAME LAN14
-> ALTER SUBNET SN1, FAMILY INET6, IPV6 UP
-> ALTER SUBNET $ZZTCP.*.SN1, FAMILY INET6, &
ADDIPV6PREFIX "DEC:5::/64"

To remove all IPv6 configuration parameters from SN1, including all IPv6
addresses and IPv6 routes through the SUBNET:
-> ALTER SUBNET $ZZTCP.*.SN1, FAMILY INET6, IPV6 DOWN
To reenable IPv6 functionality on SUBNET SN1, you must use the ALTER
SUBNET to reenable the SUBNET SN1 for IPv6 and readd the prefix "DEC:5::/64".
Automatic Tunneling Example
This command sequence implements automatic tunneling on one side of a connection
between two hosts. First, an ADD SUBNET command configures an IPv4 (FAMILY
INET) SUBNET. ALTER SUBNET command then enables that SUBNET for use with
IPv6. Finally, another ALTER SUBNET command, issued to the TUN object, activates
tunnelling.
-> ASSUME PROCESS $ZZTCP
-> ADD SUBNET PROCESS SN1, TYPE ETHERNET, &
IPADRESS 172.17.217.232, FAMILY INET, &
DEVICENAME LAN01
-> ALTER SUBNET SN1, FAMILY INET6, IPV6 UP
