T0100-01, Revision B
This section highlights routing features and protocols supported by the Vanguard IP
Applications Ware.
The Internet Protocol is a connectionless packet delivery protocol that performs
addressing, delivery, processing and control for transporting data packets over a
network.
Motorola's implementation of IP Routing supports these protocol and features:
• ARP (Address Resolution Protocol)
• RIP version 1 and version 2 (Routing Information Protocol)
• On Demand RIP
• OSPF
• Default Gateway and Default Subnet Gateway
• IP Broadcast Handling
• IP Multicast Routing - IGMP (Internet Group Multicast Protocol) and
DVMRP support
• IP Address Filtering and Access Control
• ICMP Router Discovery
• Proxy Routing
• Network Address Translation (NAT)
• Class Inter-Domain Routing (CIDR) for OSPF and static routes
In addition, Motorola IP implementation also offers bandwidth management
solutions to maximize network performance and availability. These solutions offer:
• Dial on demand routing
• IP load balancing
• Bandwidth on demand
• Data compression
• Bandwidth allocation
• Time of Day link control
• Traffic and Protocol prioritization
The Vanguard supports Open Short Path First Protocol (OSPF) defined by RFC 1583
version 2. OSPF is an Interior Gateway Protocol (IGP) used to distribute information
among routers belonging to an autonomous system (AS). Vanguard implementation
of OSPF offers:
• TOS routing - Packet routing based on Type of Service (TOS)
• Variable Length Subnet Masks — Lets you break an IP address into variable
size subnets, conserving IP address space.
• Routing authentication — Provides additional routing security
• CIDR - Classless Interdomain Routing
• IP subnetting and the tagging of externally derived routing information. It
uses IP multicast when sending or receiving packets.
