IP Routing
The XP 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 XP supports the following IP multicast routing protocols:
•
IGMP
•
DVMRP
The XP 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 XP 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 XP when an IPX interface is created.
Layer-4 Switching
In addition to Layer-2 bridging and Layer-3 routing, the XP performs Layer-4 switching.
Layer-4 switching is based on applications and flows.
•
Layer-4 applications – The XP 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 XP looks at the packet's TCP or UDP port number
to determine the application. For IPX packets, the XP looks at the destination socket to
determine the application.
•
Layer-4 flows – The XP can store Layer-4 flows on each line card. A Layer-4 flow
consists of the source and destination addresses in the IP or IPX packet combined with
