Features
IP Routing
The X-Pedition supports the following IP unicast routing protocols:
• RIP v1 and RIP v2
• OSPF v2
• BGP 2,3,4
IP interfaces do not use a specific routing protocol by default. When you configure an interface for
routing, you also specify the routing protocol the interface will use.
IP Multicast Routing
The X-Pedition supports the following IP multicast routing protocols:
• IGMP
• DVMRP
• PIM-SM
The X-Pedition does not use a specific IP Multicast routing protocol by default. When you
configure an interface for IP Multicast, you also specify the routing protocol you want the interface
to use.
IPX Routing
The X-Pedition supports the following IPX routing protocols:
• IPX RIP – a version of the Routing Information Protocol (RIP) tailored for IPX
• IPX SAP – the Service Advertisement Protocol, which allows hosts attached to an IPX network
to reach printers, file servers, and other services
By default, IPX routing is enabled on the X-Pedition when an IPX interface is created.
Layer-4 Switching
In addition to Layer-2 bridging and Layer-3 routing, the X-Pedition performs Layer-4 switching.
Layer-4 switching is based on applications and flows.
• Layer-4 applications – The X-Pedition understands the application for which an IP or IPX
packet contains data and therefore enables you to manage and control traffic on an application
basis. For IP traffic, the X-Pedition looks at the packet’s TCP or UDP port number to determine
the application. For IPX packets, the X-Pedition looks at the destination socket to determine the
application.
