Basic IP conguration
IP is enabled by default. Basic conguration consists of adding IP addresses for Layer 3 switches, enabling a route exchange protocol,
such as the Routing Information Protocol (RIP).
NOTE
The terms Layer 3 switch and router are used interchangeably in this chapter and mean the same.
NOTE
References to chassis-based Layer 3 switches apply to the FSX 800 and FSX 1600.
If you are conguring a Layer 3 switch, refer to Conguring IP addresses on page 37 to add IP addresses, then enable and congure
the route exchange protocols, as described in other chapters of this guide.
If you are conguring a Layer 2 switch, refer to Conguring the management IP address and specifying the default gateway on page
95 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 congure 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 conguration information or statistics.
IP conguration overview
Brocade Layer 2 switches and Layer 3 switches support Internet Protocol version 4 (IPv4) and IPv6. IP support on Brocade Layer 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
congurable 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)
