SLAAC Configuration

The basic configuration of SLAAC on a Cisco device is quite simple. The required steps are shown in Table 1.

Table 1: Basic IPv6 SLAAC Configuration

1

Enter privileged EXEC mode

Router>enable

2

Enter global configuration mode

Router#configure terminal

4

Enable IPv6 routing

Router(config)#ipv6 unicast-routing

4

Enter interface configuration mode

Router(config)#interface interface

5

Configure an IPv6 address

Router(config-if)#ipv6 address ipv6-address/prefix-length

6

Enable the interface

Router(config-if)#no shutdown

To bring this together with the example topology shown in Figure 1, the required commands to configure R1 are shown in Table 2.

Table 2: Basic IPv6 SLAAC Example Configuration

1

Enter privileged EXEC mode

R1>enable

2

Enter global configuration mode

R1#configure terminal

4

Enable IPv6 routing

R1(config)#ipv6 unicast-routing

4

Enter interface configuration mode

R1(config)#interface fa0/0

5

Configure an IPv6 address

R1(config-if)#ipv6 address 2000:1234:5678::1001:1/64

6
