What is the purpose of Slaac?

What is the purpose of Slaac?

SLAAC stands for Stateless Address Autoconfiguration and the name pretty much explains what it does. It is a mechanism that enables each host on the network to auto-configure a unique IPv6 address without any device keeping track of which address is assigned to which node.

Does Slaac use DNS?

DNS considerations for IPv6 SLAAC SLAAC allows IPv6 end-nodes to choose their own addresses and is defined in RFC 4862. This concerns DNS because when clients create their own IPv6 addresses via SLAAC DNS still needs to have reverse DNS records for these addresses.

Is Slaac safe?

SECURITY POLICIES: As clear from above section, SLAAC can be a huge risk once the host machines get configured by a malicious router and this can directly target privacy and security of data on the network.

How do you set up Slaac?

The basic configuration of SLAAC on a Cisco device is quite simple….Table 2: Basic IPv6 SLAAC Example Configuration.

1 Enter privileged EXEC mode R1>enable
5 Configure an IPv6 address R1(config-if)#ipv6 address 2000:1234:5678::1001:1/64
6 Enable the interface R1(config-if)#no shutdown

What protocols does Slaac use?

SLAAC Defined. Like IPv4, there are a number of different ways that a host can be addressed in IPv6; the two most common in IPv4 are static addressing and dynamic address configuration via the Dynamic Host Configuration Protocol (DHCP).

How do I enable Slaac?

Enable IPv6 SLAAC on Cisco Routers

  1. Step-1. Enable IPv6 Routing on R6.
  2. Step-2. Enable IPv6 and Add prefix on R6: interface Ethernet0/1. ip address 192.168.100.10 255.255.255.0.
  3. Step-3. Enable IPv6 Routing on R1. R1(config)#ipv6 unicast-routing.
  4. Step-4. Enable IPv6 and configure IPv6 auto-config R1: interface Ethernet0/0.
