Migrating from DHCPv6 1.001 to DHCPv6

2.001

This chapter discusses the steps to migrate from DHCPv6 1.001 to

DHCPv6 2.001 when you have conﬁgured your system as a client, server,

or relay agent.

NOTE Before migrating to DHCPv6 2.001, you may ﬁnd it useful to read the

DHCPv6 2.001 Release Notes at http://www.docs.hp.com.

Migrating a DHCPv6 1.001 Server

If you have conﬁgured your system as a server or client using DHCPv6

1.001, complete the following steps to migrate from DHCPv6 1.001 to

DHCPv6 2.001 after installing the DHCPv6 2.001 software depot on your

system:

Step 1. If you have conﬁgured IPv6 addresses for an interface using DHCPv6

1.001, you must unconﬁgure the IPv6 addresses using the ifconfig

(1M) utility.

Step 2. Move the tags address-pool, subnet-prefix, and

reserved-addresses from the DHCP_POOL_GROUP section to the

DHCP_ADDRESS_POOL section in the /etc/dhcpv6tab conﬁguration ﬁle.

You can specify multiple DHCP_ADDRESS_POOL settings for a single

DHCP_POOL_GROUP.

For example, consider the following DHCPv6 1.001 pool group

conﬁguration in the /etc/dhpv6tab conﬁguration ﬁle:

DHCP_POOL_GROUP;\

pool-group-name = YELLOW;\

subnet-prefix = 5ffe:1234::34;\

prefix-length = 64;\

address-pool = 5ffe:1234::4321:1000 -

5ffe:1234::4321:9999;\

reserved-addresses = 5ffe:1234::4321:1222;
