Brocade FastIron Ethernet Switch Layer 3 Routing Configuration Guide - Manual (Page 23)

If you are configuring a Layer 2 switch, refer to Configuring the management IP address and specifying
the default gateway on page 105 to add an IP address for management access through the network
and to specify the default gateway.
The rest of this chapter describes IP and how to configure it in more detail. Use the information in this
chapter if you need to change some of the IP parameters from their default values or you want to view
configuration information or statistics.
IP configuration overview
Brocade Layer 2 switches and Layer 3 switches support Internet Protocol version 4 (IPv4) and IPv6. IP
support on BrocadeLayer 2 switches consists of basic services to support management access and
access to a default gateway.
Full Layer 3 support
IP support on Brocade full Layer 3 switches includes all of the following, in addition to a highly
configurable implementation of basic IP services including Address Resolution Protocol (ARP), ICMP
Router Discovery Protocol (IRDP), and Reverse ARP (RARP):
• Route exchange protocols:
‐ Routing Information Protocol (RIP)
‐ Open Shortest Path First (OSPF)
‐ Border Gateway Protocol version 4 (BGP4)
• Multicast protocols:
‐ Internet Group Membership Protocol (IGMP)
‐ Protocol Independent Multicast Dense (PIM-DM)
‐ Protocol Independent Multicast Sparse (PIM-SM)
• Router redundancy protocols:
‐ Virtual Router Redundancy Protocol Extended (VRRP-E)
‐ Virtual Router Redundancy Protocol (VRRP)
IP interfaces
NOTE
This section describes IPv4 addresses. For information about IPv6 addresses on FastIron X Series
devices, refer to "IPv6 addressing overview" section in the FastIron Ethernet Switch Administration
Guide .
Brocade Layer 3 switches and Layer 2 switches allow you to configure IP addresses. On Layer 3
switches, IP addresses are associated with individual interfaces. On Layer 2 switches, a single IP
address serves as the management access address for the entire device.
All Brocade Layer 3 switches and Layer 2 switches support configuration and display of IP addresses in
classical subnet format (for example: 192.168.1.1 255.255.255.0) and Classless Interdomain Routing
(CIDR) format (for example: 192.168.1.1/24). You can use either format when configuring IP address
information. IP addresses are displayed in classical subnet format by default but you can change the
display format to CIDR. Refer to
Changing the network mask display to prefix format on page 132.
