Basic IPv6 configuration with SLAAC

‎04-30-2012 07:51 AM

 

We want to translate basic IPv6 configuration with SLAAC (Stateless Address Auto-Configuration) from IOS to Junos.

No advanced routing, just basic IPv6 connectivity and SLAAC for hosts autoconfiguration. 

 

In IOS we have:

ipv6 unicast-routing
!
interface FastEthernet1
 ipv6 address 2001:DB8:C0C0::123/64
!

 

Junos version:

ge-1/3/0 {
    unit 0 {
        family inet6 {
            address 2001:db8:c0c0::123/64;
        }
    }
}

protocols {
    router-advertisement {
        interface ge-1/3/0.0 {
            prefix 2001:db8:c0c0::/64;
        }
    }
}

 

Notes:

  • IOS - we need to enable IPv6 forwarding  (ipv6 unicast-routing) explicitly 
  • Junos - to enable SLAAC we need to explicitly configure router-advertisement and list the interface prefix(es)
