Avaya X330WAN manual Layer 3 Features, Convergence Features

Features

•Point-to-Point Frame Relay encapsulation over channelized/fractional/unframed E1/T1 ports or over a USP interface.

•Frame Relay LMI types supported: ANSI (Annex D), ITU-T:Q-933 (Annex A0), LMI-Rev1, and No LMI.

•Backup functionality supported between any type of Serial Layer 2 interface. For more information refer to "Backup Interfaces" on page 44.

•Up to 253 VLANs on the FabricFastEthernet LAN interface. VLANs assigned on the FabricFastEthernet port enable the X330WAN to perform inter-VLAN routing. Specific VLANs can be configured to have access to the WAN while others can be configured to deny such access.

•Auto-Negotiation - the Fast Ethernet port supports Auto-Negotiation that automatically detects and supports the duplex mode and speed of a connected device. X330WAN can be connected to Ethernet or Fast Ethernet equipment at full or half duplex without any further configuration.

Layer 3 Features

•RIP v1/v2 routing protocols.

•Single Area OSPF routing protocol - X330WAN can be configured as an OSPF Autonomous System Boundary Router (ASBR) by configuring route redistribution. You can install X330WAN in the OSPF backbone area (area 0.0.0.0) or in any OSPF area that is part of a multiple areas network. X330WAN can not be configured to be an OSPF area border router.

•VRRP redundancy protocol - supported only on the X330WAN’s LAN (Fast Ethernet and FabricFastEthernet) ports.

•Equal-Cost MultiPath (ECMP) - enables load balancing by splitting traffic between several equivalent paths.

•Enhanced routing configuration for efficient bandwidth usage, including RIP Distribution Lists. For more information, refer to "Enhanced Routing Capabilities" on page 35.

Convergence Features

•Quality of Service (QoS) - X330WAN supports the ability to separate traffic into 4 strict priority queues per egress serial interface. The queue assignment is performed using Policy. For more detailed information, refer to "Frame Relay Encapsulation" on page 46.

•Guaranteed delay for VoIP traffic - X330WAN supports VoIP Queue mode. In this mode traffic labelled as voice traffic receives preference over all other traffic. The X330WAN default VoIP queuing mode is optimized for the G.729 CODEC. For more detailed information, refer to "Frame Relay Encapsulation" on page 46.
