Chapter 17 6RD Configuration

A CE assigns the IPv6 address of the CE LAN side to a downstream user through DHCPv6

or SLAAC based on the prefix.

Message Forwarding

Forwarding a message in a 6rd domain

As shown in

Figure 17-4

, upon arrival of a message from PC1, CPE1 obtains the IPv4

address from the IPv6 destination address after a decapsulation, encapsulates the

message into a 6in4 tunnel, and forwards it to CPE2. Upon receipt of the message,

CPE2 obtains the raw message after a decapsulation, and forwards it to PC3. PC1

and PC2 can be on the same IPv6 subnet. The blue line in

Figure 17-4

illustrates the

message forwarding direction.

Figure 17-4 Forwarding a Message in a 6rd Domain

CPE1 works as follows.

Upon receipt of a message destined for 2001:db8:0a0a:100::0:0202:0202, CPE1

determines that the next-hop is the tunnel based on the IPv6 route (::/0 -> tunnel1

via 2001:db8:0:100:).

The IPv6 destination address indicates that this IPv6 message is addressed to

the same domain. CPE1 then encapsulates the message into a tunnel with the

carried IPv4 address being the destination address.

Search the route, and forward the message to CPE2.

CPE2 works as follows.

Upon detecting a 6rd label on the IPV4 route, CPE2 decapsulates the received

IPv4 message, and obtains the raw IPv6 message.

Forward the raw IPv6 message to (2001:db8:0a0a:100::0:0202:0202).

Forwarding a message out of a 6rd domain

As shown in

Figure 17-5

, upon receipt of a message from PC1, CPE1 determines that

the message is addressed to an out-of-domain area by matching the IPv6 prefix. It

then encapsulates the message into a 6in4 tunnel with the destination address being
