Chapter 1 Getting to know your BCM50a Integrated Router 35
BCM50a Integrated Router Configuration — Advanced
IP Multicast
The BCM50a Integrated Router can use IP multicast to deliver IP packets to a
specific group of hosts. IGMP (Internet Group Management Protocol) is the
protocol used to support multicast groups. The BCM50a Integrated Router
supports versions 1 and 2.
IP Alias
Using IP Alias, you can partition a physical network into logical networks over
the same Ethernet interface. The BCM50a Integrated Router supports three
logical LAN interfaces through its single physical Ethernet LAN interface with
the BCM50a Integrated Router itself as the gateway for each LAN network.
Central Network Management
With Central Network Management (CNM), an enterprise or service provider
network administrator can manage your BCM50a Integrated Router. The
enterprise or service provider network administrator can configure your BCM50a
Integrated Router, perform firmware upgrades, and do troubleshooting for you.
SNMP
SNMP (Simple Network Management Protocol) is a protocol used for exchanging
management information between network devices. SNMP is a member of the
TCP/IP protocol suite. Your BCM50a Integrated Router supports SNMP agent
functionality, which means that a manager station can manage and monitor the
BCM50a Integrated Router through the network. The BCM50a Integrated Router
supports SNMP versions 1 and 2 (SNMPv1 and SNMPv2).
Network Address Translation (NAT)
NAT (Network Address Translation — NAT, RFC 1631) translate multiple IP
addresses used within one network to different IP addresses known within another
network.
