IPv4 Routing

IPv4 routing is supported on the Z9000 platform.

The Dell Networking Operating System (OS) supports various IP addressing features. This chapter

describes the basics of domain name service (DNS), address resolution protocol (ARP), and routing

principles and their implementation in the Dell Networking OS.

ICMP Unreachable Disabled

ICMP Redirect

Dell Networking OS supports IP version 4, as described in RFC 791. Dell Networking OS also supports

classful routing and variable length subnet masks (VLSM).

With VLSM, you can configure one network with different masks. Supernetting, which increases the

number of subnets, is also supported. To subnet, you add a mask to the IP address to separate the

network and host portions of the IP address.

At its most basic level, an IP address is 32-bits composed of network and host portions and represented

in dotted decimal format. For example, 00001010110101100101011110000011 is represented as

10.214.87.131.

For more information about IP addressing, refer to RFC 791, Internet Protocol.

In Dell Networking OS, you can configure any IP address as a static route except IP addresses already

assigned to interfaces.

NOTE: Dell Networking OS supports 31-bit subnet masks (/31, or 255.255.255.254) as defined by

RFC 3021. This feature allows you to save two more IP addresses on point-to-point links than 30-bit

masks. Dell Networking OS supports RFC 3021 with ARP.

The following describes the tasks associated with IP address configuration.

Configuration tasks for IP addresses includes:
