4.
Configure IGMP.
To enable IGMP on the router, and on the interfaces over which group
membership will be managed, enter the commands:
ENABLE IP IGMP
ENABLE IP IGMP INTERFACE=ETH0
ENABLE IP IGMP INTERFACE=FR0
5.
Configure DVMRP.
To enable DVMRP on the router, and on the interfaces over which DVMRP
will perform multicast routing, enter the commands:
ENABLE DVMRP
ADD DVMRP INTERFACE=ETH0 METRIC=1
ADD DVMRP INTERFACE=FR0 DLC=20 METRIC=6
Confirm multicasting.
When you have configured the three routers, the IP hosts connected to these
interfaces can send and receive multicasts packets.
1.
Test multicasting.
Send IP multicast data between hosts connected to each of the routers to
test whether IP multicasting is successful.
2.
Check the configuration.
To check the configuration on each router, use the commands:
SHOW DVMRP
SHOW IP IGMP
SHOW IP ROUTE MULTICAST
For more information on how to configure IP Multicasting, including PIM-SM
and PIM-DM, see the IP Multicasting chapter in the AR400 Series Router Software
Reference.
Configuring Dynamic Host Configuration
Protocol (DHCP)
DHCP provides a method for passing configuration information to hosts on a
TCP/IP network. DHCP is based on its predecessor Bootstrap Protocol
(BOOTP), but adds automatic allocation of reusable network addresses and
additional configuration options.
When the router is configured as a DHCP server, it will allocate IP addresses
and other IP configuration parameters to clients (hosts), when the client
requests them. This enables you to configure your IP network without
manually configuring every client. Note that each client must also be
configured to receive its IP address automatically.
As well as addresses, a DHCP server can assign a wide range of parameters to
clients, including subnet information and mask, domain and hostname, server
addresses, keepalive times, MTUs, boot settings, encapsulation settings, time
settings, and TCP settings.
