BLADEOS 6.5.2 Application Guide
BMD00220, October 2010 Chapter 16: Internet Protocol Version 6 239
Configuration Guidelines
When you configure an interface for IPv6, consider the following guidelines:
IPv6 only supports static routes.
Support for subnet router anycast addresses is not available.
A single interface can accept either IPv4 or IPv6 addresses, but not both IPv4 and IPv6
addresses.
A single interface can accept multiple IPv6 addresses.
A single interface can accept only one IPv4 address.
If you change the IPv6 address of a configured interface to an IPv4 address, all IPv6 settings
are deleted.
A single VLAN can support only one IPv6 interface.
Health checks are not supported for IPv6 gateways.
IPv6 interfaces support Path MTU Discovery. The CPU’s MTU is fixed at 1500 bytes.
Support for jumbo frames (1,500 to 9,216 byte MTUs) is limited. Any jumbo frames intended
for the CPU must be fragmented by the remote node. The switch can re-assemble fragmented
packets up to 9k. It can also fragment and transmit jumbo packets received from higher layers.
