In addition to the embedded DHCP local server that is used for IP version 4 (IPv4) address
support, E Series routers include an embedded DHCPv6 local server. This server enables
the router to function as a server for the DHCP protocol for IP version 6 (IPv6). The
DHCPv6 local server sends and receives packets via IPv6 and informs IPv6 of the routing
requirements of the router clients.
The DHCPv6 local server provides the following IPv6 address support:
Delegates IPv6 prefixes to client routers; each client can have one prefix; prefixes and
DNS information can be locally configured or derived from RADIUS via AAA.
Provides DNS server information to directly connected router clients.
NOTE: You must add a vendor-specific attribute to RADIUS to enable
E Series routers to retrieve IPv6 Domain Name System (DNS) addresses.
Use the following steps to configure the DHCPv6 local server:
Enable the DHCPv6 local server.
1.
host1(config)#service dhcpv6-local
Specify the IPv6 prefix and lifetime that are to be delegated to the DHCPv6 client.
2.
The specified prefix is delegated by the DHCPv6 local server when requested by the
client.
host1(config-if)#ipv6 dhcpv6-local delegated-prefix 2001:db8:17::/48 lifetime infinite
Use the lifetime keyword to specify the time period for which the prefix is valid. This
lifetime overrides the default lifetime that is set in Global Configuration mode. If no
lifetime is specified, the default lifetime is assigned.
Specify the number of days and, optionally, the number of hours, minutes, and
seconds. You cannot specify a lifetime of zero (that is, you cannot set the days,
hours, minutes, and seconds fields all to zero).
