24 ExtremeWare XOS 11.0 Concepts Guide
ExtremeWare XOS Overview
VRRP
Similar to ESRP, the Virtual Router Redundancy Protocol (VRRP) allows switches to provide redundant
routing services. With software version 11.0, ExtremeWare XOS supports VRRP.
If a manually configured default gateway fails and you are not using VRRP, you must reconfigure each
host on the network to use a different router. If the default gateway fails when running VRRP, the
backup router assumes forwarding responsibilities.
NOTE
IGMP snooping must be enabled to operate VRRP correctly.
For more information on VRRP, see Chapter 14.
IP Multicast Routing
The switch can use IP multicasting to allow a single IP host to transmit a packet to a group of IP hosts.
ExtremeWare XOS supports multicast routes that are learned by the Protocol Independent Multicast
(PIM) (dense mode or sparse mode).
For more information on IP multicast routing, see Chapter 18.
