page, the router will block it.
Example:
Refer to the following example.
1.
Use TSPC mode to connect to IPv6 network.
PC get ipv6 IP: 2001:5c0:1503:7400:30e4:139d:53c8:3a1e
2.
Connect PC to http://www.ipv6.org/
with IPv6 IP address.
A message will appear from the web page:
Welcome to the IPv6 Information Page!
You are using IPv6 from 2001:5c0:1503:7400:30e4:139d:53c8:3a1e
3.

4.10.4 IPv6 Routing
This page displays the routing table for the protocol of IPv6.
Device
Display the
interface name (eth0, eth1, fp, etc..)that
used to transfer packets with addresses matching the
prefix.
Prefix
The IPv6 address prefix.
Metric
Display the
distance to the target (usually counted in
hops). It is not used by recent kernels, but may be
needed by routing daemons.
Expires
Display the lifetime of the route.
MTU
Display t
he largest size (in bytes) of a packet.

Advmss
Display t
he largest size (in bytes) of an unfragmented
piece of a routing advertisement.
Hoplimit
Display t
he number of network segments on which the
packet is allowed to travel before discarded.
Auto-refresh

at regular intervals.
4.10.5 IPv6 Neighbour
IPv6 uses neighbor discovery protocol to find out neighbors on the same link.
Device
The interface name of the link where the neighbor is on.
IP Address
The IPv6 address of the neighbor.
MAC Address
The link-layer address of the neighbor.
State
Possible states include:
incomplete
- address resolution is in progress.
reachable
- neighbor is reachable.
stale
– neighbor(s) may be unreachable but not verified
until a packet is sent).
delay
- neighbor may be unreachable and a packet was sent.
probe
- neighbor may be unreachable and probes are sent
to verify the reachability.
Auto-refresh
Check this box to enable an automatic refresh of the page
at regular intervals.
4.10.6 IPv6 TSPC Status
IPv6 TSPC status web page could help you to diagnose the connection status of TSPC. TSPC
log contains some debug information from program.
If TSPC has not configured properly, the router will display the following page when the user
tries to connect through TSPC connection.

When TSPC configuration has been done, the router will start to connect. The connecting page
will be shown as below:
When the router detects all the information, the screen will be shown as follows. One set of
TSPC prefix
and
prefix length
will be obtained after the connection between TSPC and
Tunnel broker built.
Connection Status
It will bring out different pages to represent IPv6
disconnection, connecting and connected.
