IPv6 management (IPv6 host support)
Configuring an IPv6 anycast address on an interface
In IPv6, an anycast address is an address for a set of interfaces belonging to different nodes.
Sending a packet to an anycast address results in the delivery of the packet to the closest interface
configured with the anycast address.
An anycast address looks similar to a unicast address, because it is allocated from the unicast
address space. If you assign an IPv6 unicast address to multiple interfaces, it is an anycast
address. On the device, you configure an interface assigned an anycast address to recognize the
address as an anycast address.
For example, the following commands configure an anycast address on interface 1.
TurboIron(config)#int e 1
TurboIron(config-if-e10000-1)#ipv6 address 2001:DB8::/64 anycast
Syntax: ipv6 address <ipv6-prefix> / <prefix-length> [ anycast ]
IPv6 anycast addresses are described in detail in RFC 1884. See RFC 2461 for a description of
how the IPv6 Neighbor Discovery mechanism handles anycast addresses.
IPv6 management (IPv6 host support)
An IPv6 host has IPv6 addresses on its interfaces, but does not have full IPv6 routing enabled on it.
Restricting SNMP access to an IPv6 node
You can restrict SNMP access to the device to the IPv6 host whose IP address you specify. To do
so, enter a command such as the following.
TurboIron(config)#snmp-client ipv6 2001:DB8:89::23
Syntax: snmp-client ipv6 <ipv6-address>
• The <ipv6-address> you specify must be in hexadecimal format using 16-bit values between
colons as documented in RFC 2373.
Specifying an IPv6 SNMP trap receiver
You can specify an IPv6 host as a trap receiver to ensure that all SNMP traps sent by the device will
go to the same SNMP trap receiver or set of receivers, typically one or more host devices on the
network. To do so, enter a command such as the following.
TurboIron(config)#snmp-server host ipv6 2001:DB8:89::13
Syntax: snmp-server host ipv6 <ipv6-address>
• The <ipv6-address> you specify must be in hexadecimal format using 16-bit values between
colons as documented in RFC 2373.
SNMP V3 over IPv6
TurboIron X Series devices support IPv6 for SNMP version 3. For more information about how to
configure SNMP, refer to
“Securing SNMP Access” on page 163.
