CCNA Portable Command Guide: IPv6

Chapter Description

This chapter provides information and commands concerning a number of IPv6-related topics such as assigning IPv6 addresses to interfaces, IPv6 tunnels, and IPv6 ping.

Configuration Example: IPv6 RIP

Figure 25-1 illustrates the network topology for the configuration that follows, which shows how to configure IPv6 and RIPng using the commands covered in this chapter.

Figure 25-1 Network Topology for IPv6/RIPng Configuration Example

Austin Router

Router>enable

Moves to privileged mode

Router#configure terminal

Moves to global configuration mode

Router(config)#hostname Austin

Assigns a host name to the router

Austin(config)#ipv6 unicast-routing

Enables the forwarding of IPv6 unicast datagrams globally on the router

Austin(config)#interface fastethernet 0/0

Enters interface configuration mode

Austin(config-if)#ipv6 enable

Automatically configures an IPv6 link-local address on the interface and enables IPv6 processing on the interface

Austin(config-if)#ipv6 address 2001:db8:c18:2::/64 eui-64

Configures a global IPv6 address with an interface identifier in the low-order 64 bits of the IPv6 address

Austin(config-if)#ipv6 rip tower enable

Creates the RIPng process named tower and enables RIPng on the interface

Austin(config-if)#no shutdown

Activates the interface

Austin(config-if)#interface fastethernet 0/1

Enters interface configuration mode

Austin(config-if)#ipv6 enable

Automatically configures an IPv6 link-local address on the interface and enables IPv6 processing on the interface

Austin(config-if)#ipv6 address 2001:db8:c18:1::/64 eui-64

Configures a global IPv6 address with an interface identifier in the low-order 64 bits of the IPv6 address

Austin(config-if)#ipv6 rip tower enable

Creates the RIPng process named tower and enables RIPng on the interface

Austin(config-if)#no shutdown

Activates the interface

Austin(config-if)#exit

Moves to global configuration mode

Austin(config)#exit

Moves to privileged mode

Austin#copy running-config startup-config

Saves the configuration to NVRAM

Houston Router

Router>enable

Router(config)#hostname Houston

Assigns a host name to the router

Houston(config)#ipv6 unicast-routing

Enables the forwarding of IPv6 unicast datagrams globally on the router

Houston(config)#interface fastethernet 0/0

Enters interface configuration mode

Houston(config-if)#ipv6 enable

Automatically configures an IPv6 link-local address on the interface and enables IPv6 processing on the interface

Houston(config-if)#ipv6 address 2001:db8:c18:2::/64 eui-64

Configures a global IPv6 address with an interface identifier in the low-order 64 bits of the IPv6 address

Houston(config-if)#ipv6 address 2001:db8:c18:3::/64 eui-64

Configures a global IPv6 address with an interface identifier in the low-order 64 bits of the IPv6 address

Houston(config-if)#ipv6 rip tower enable

Creates the RIPng process named tower and enables RIPng on the interface

Houston(config-if)#no shutdown

Activates the interface

Houston(config-if)#exit

Moves to global configuration mode

Houston(config)#exit

Moves to privileged mode

Houston#copy running-config startup-config

Saves the configuration to NVRAM
