Overview
• Route exchange protocols:
• Routing Information Protocol (RIP)
• Open Shortest Path First (OSPF)
• 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
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 Layer 3 Switches and Layer 2 Switches support configuration and display of IP address in
classical subnet format (example: 192.168.1.1 255.255.255.0) and Classless Interdomain
Routing (CIDR) format (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 492.
Layer 3 Switches
Layer 3 Switches allow you to configure IP addresses on the following types of interfaces:
• Ethernet ports
• Virtual routing interfaces (used by VLANs to route among one another)
• Loopback interfaces
Each IP address on a Layer 3 Switch must be in a different subnet. You can have only one interface
that is in a given subnet. For example, you can configure IP addresses 192.168.1.1/24 and
192.168.2.1/24 on the same Layer 3 Switch, but you cannot configure 192.168.1.1/24 and
192.168.1.2/24 on the same Layer 3 Switch.
You can configure multiple IP addresses on the same interface.
The number of IP addresses you can configure on an individual interface depends on the Layer 3
Switch model. To display the maximum number of IP addresses and other system parameters you
can configure on a Layer 3 Switch, refer to the section
“Displaying and modifying system parameter
default settings” on page 265.
You can use any of the IP addresses you configure on the Layer 3 Switch for Telnet or SNMP access.
Layer 2 Switches
You can configure an IP address on a Layer 2 Switch for management access to the Layer 2 Switch.
An IP address is required for Telnet access and SNMP access.
