• Metric—Value used for comparing this route to other routes with the same destination
in the IPv6 router table. All default routes have the same value.
• Lifetime—Time period during which the packet can be sent, and resent, before being
deleted.
• Route Type—How the destination is attached, and the method used to obtain the entry.
The following values are:
- S (Static) —Entry was manually configured by a user.
- I (ICMP Redirect)—Entry is an ICMP redirect dynamic route received from an
IPv6 router by using ICMP redirect messages.
- ND (Router Advertisement)—Entry is taken from a router advertisement message.
To add a new route, click Add and enter the fields described above. In addition, enter the
following field:
• IPv6 Address—Add the IPv6 address of the new route.
Click Apply to save the changes.
DHCPv6 Relay
This section covers the following topics:
• Global Destinations
• Interface Settings
DHCPv6 Relay is used for relaying DHCPv6 messages to DHCPv6 servers. It is defined in
RFC 3315.
When the DHCPv6 client is not directly connected to the DHCPv6 server, a DHCPv6 relay
agent (the device) to which this DHCPv6 client is directly-connected encapsulates the
received messages from the directly-connected DHCPv6 client, and forwards them to the
DHCPv6 server.
In the opposite direction, the relay agent decapsulates packets received from the DHCPv6
server and forwards them, towards the DHCPv6 client.
The user must configure the list DHCP servers to which packets are forwarded. Two sets of
DHCPv6 servers can be configured:
• Global Destinations—Packets are always relayed to these DHCPv6 servers.
