Host versus router

Each IPv6 interface can be configured as a router node or a host node, as follows:

򐂰 A router node’s IP address is configured manually. Router nodes can send

Router Advertisements.

򐂰 A host node’s IP address is auto-configured. Host nodes listen for Router Advertisements

that convey information about devices on the network.

You can configure each IPv6 interface as either a host node or a router node. You can

manually assign an IPv6 address to an interface in host mode, or the interface can be

assigned an IPv6 address by an upstream router, using information from router

advertisements to perform stateless auto-configuration.

2.5.5 IPv6 support

IBM System Networking switches running IBM Networking OS V6.8 support IPv6 features

included in the following IETF RFCs:

򐂰 RFC 2740 for OSPF

򐂰 RFCs 3306 and 3307 for dynamic IPv6 multicast addresses

򐂰 RFC 3810 for Multicast Listener Discovery (MLDv2)

򐂰 RFC 4301 for IPv6 security

򐂰 RFC 4302 for the IPv6 Authentication Header

򐂰 RFCs 2404, 2410, 2451, 3602, and 4303 for IPv6 Encapsulating Security Payload (ESP),

including NULL encryption, CBC-mode 3DES and AES ciphers, and HMAC-SHA-1-96.

򐂰 RFCs 4306, 4307, 4718, and 4835 for Internet Key Exchange (IKEv2) and cryptography

򐂰 RFC 4552 for OSPFv3 IPv6 authentication

򐂰 RFC 5114 for Diffie-Hellman groups

2.6 Monitoring

In this section, we describe different features available in IBM System Networking switches

that can be used to monitor characteristics of forwarded traffic or characteristics of the

switch itself.

2.6.1 Port mirroring

You can use the IBM System Networking switches port mirroring feature to mirror (copy) the

packets of a target port, and forward them to a monitoring port. Port mirroring functions for all

Layer 2 and Layer 3 traffic on a port. This feature can be used as a troubleshooting tool or to

enhance the security of your network.

IP forwarding: When IP forwarding is turned on. All IPv6 interfaces configured on the

switch can forward packets.
