IPv6 connectivity overview
This chapter explains how to get a Brocade Layer 3 Switch that supports IPv6 up and running. To
configure basic IPv6 connectivity, you must do the following:
• Enable IPv6 routing globally on the Brocade Layer 3 Switch.
• Configure an IPv6 address or explicitly enable IPv6 on each router interface over which you
plan to forward IPv6 traffic.
• Configure IPv4 and IPv6 protocol stacks. (This step is mandatory only if you want a router
interface to send and receive both IPv4 and IPv6 traffic.)
The following configuration tasks are optional:
• Configure IPv6 Domain Name Server (DNS) resolver
• Configure ECMP Load Sharing for IPv6
• Configure IPv6 ICMP.
