Veritas Storage Foundation 5.1 SP1 Cluster File System Installation Guide (5900-1510, April 2011)

Configuring LLT over UDP

using IPv6

This appendix includes the following topics:

■ Using the UDP layer of IPv6 for LLT

■ Manually configuring LLT over UDP using IPv6

Using the UDP layer of IPv6 for LLT

Veritas Storage Foundation Cluster File System 5.1 SP1 provides the option of

using LLT over the UDP (User Datagram Protocol) layer for clusters using wide-area

networks and routers. UDP makes LLT packets routable and thus able to span

longer distances more economically.

When to use LLT over UDP

Use LLT over UDP in the following situations:

■ LLT must be used over WANs

■ When hardware, such as blade servers, do not support LLT over Ethernet

Manually configuring LLT over UDP using IPv6

The following checklist is to configure LLT over UDP:

■ For UDP6, the multicast address is set to "-".

■ Make sure that each NIC has an IPv6 address that is configured before

configuring LLT.
