Ipv6 Disabled Mode; Table 9-17 Differences Between An Ipv6 Node And An Ipv4 Node - Cisco ONS 15600 Reference Manual

Chapter 9 Management Network Connectivity
You can manage MSTP multishelf nodes over IPv6 DCN. RADIUS, FTP, SNTP, and other network
applications support IPv6 DCN. To enable IPv6 addresses, you need to make the necessary configuration
changes from the CTC or TL1 management interface. After you enable IPv6, you can start a CTC or TL1
session using the provisioned IPv6 address. The ports used for all IPv6 connections to the node are the
same as the ports used for IPv4.
An NE can either be in IPv6 mode or IPv4 mode. In IPv4 mode, the LAN interface does not have an IPv6
address assigned to it. An NE, whether it is IPv4 or IPv6, has an IPv4 address and subnet mask.
TCC2/TCC2P cards do not reboot automatically when you provision an IPv6 address, but a change in
IPv4 address initiates a TCC2/TCC2P card reset.
node and an IPv6 node.
Table 9-17
IPv6 Node
Has both IPv6 address and IPv4 address assigned
to its craft Ethernet interface.
The default router has an IPv6 address for IPv6
connectivity, and an IPv4 address for IPv4
connectivity.
Cannot enable OSPF on LAN. Cannot change
IPv4 NE to IPv6 NE if OSPF is enabled on the
LAN.
Cannot enable RIP on the LAN. Cannot change
IPv4 NE to IPv6 NE if RIP is enabled on the LAN.
Not supported on static routes, proxy tunnels, and
firewall tunnels.
Routing decisions are based on the default IPv6
router provisioned.
Cisco ONS 15600 supports IPv6 only on the rear Ethernet interface.
Note
9.8.1 IPv6 Enabled Mode
The default IP address configured on the node is IPv4. You can use either CTC or the TL1 management
interface to enable IPv6. For more information about enabling IPv6 from the CTC interface, see the
Cisco ONS 15600 Procedure Guide. For more information about enabling IPv6 using TL1 command, see
the Cisco ONS 15454 SDH, Cisco ONS 15600 SDH, and Cisco ONS 15310 MA SDH TL1 Command
Guide.

9.8.2 IPv6 Disabled Mode

You can disable IPv6 either from the CTC or from the TL1 management interface. For more information
about disabling IPv6 from the CTC interface, see the Cisco ONS 15600 Procedure Guide. For more
information about disabling IPv6 using TL1 commands, see the Cisco ONS 15454 SDH, Cisco ONS
15600 SDH, and Cisco ONS 15310 MA SDH TL1 Command Guide.

IPv4 Node
Does not have an IPv6 address assigned to its craft
Ethernet interface.
The default router has an IPv4 address.
Can enable OSPF on the LAN.
Can enable static routes/RIP on the LAN.
Supported on static routes, proxy tunnels, and
firewall tunnels.
