The switch dynamically builds and maintains a set of routing tables and determines the best path for each of its routes. Each host using the IP unicast routing functionality of the switch must have a unique IP address assigned. In addition, the default gateway assigned to the host must be the IP address of the router interface.
The ExtremeXOS software can provide both IPv4 and IPv6 routing at the same time. Separate routing tables are maintained for the two versions. Most commands that require you to specify an IP address can accept either an IPv4 or IPv6 address and act accordingly. Additionally, many of the IP configuration, enabling, and display commands have added tokens for IPv4 and IPv6 to clarify the version required. For simplicity, existing commands affect IPv4 by default and require you to specify IPv6, so configurations from an earlier release still correctly configure an IPv4 network.
