The switch can route IP or IPX traffic between the VLANs that are configured as virtual
router interfaces. Both dynamic and static IP routes are maintained in the routing table.
The following routing protocols are supported:
• RIP version 1
• RIP version 2
• OSPF
• IPX/RIP
• BGP version 4
For more information on IP unicast routing, refer to Chapter 11. For more
information on IPX/RIP, refer to Chapter 15.

The switch can use IP multicasting to allow a single IP host to transmit a packet to a
group of IP hosts. ExtremeWare supports multicast routes that are learned by way of the
Distance Vector Multicast Routing Protocol (DVMRP) or the Protocol Independent
Multicast (dense mode or sparse mode).
For more information on IP multicast routing, refer to Chapter 14.

Load sharing allows you to increase bandwidth and resiliency by using a group of ports
to carry traffic in parallel between systems. The sharing algorithm allows the switch to
use multiple ports as a single logical port. For example, VLANs see the load-sharing
group as a single virtual port. The algorithm also guarantees packet sequencing
between clients.
