Software Release 2.7.1
C613-02047-00 REV A
Configure multicast routing using DVMRP on Router A.
1.
Set the system name.
To set a unique system name for the router, enter the command:
set sys name=a-dvmrp
2.
Configure ISDN.
To set up an ISDN call to Router C for DVMRP multicast traffic, enter the
command:
add isdn call=dvmrp number=1234567 precedence=out
outsub=local searchsub=local
3.
Configure PPP.
To create PPP interfaces over a synchronous port and the ISDN call, enter
the commands:
create ppp=0 over=syn0
create ppp=1 over=isdn-dvmrp idle=on
4.
Configure IP.
To enable the IP module, and assign IP addresses to the interfaces, enter the
commands:
enable ip
add ip interface=ppp0 ipaddress=189.124.7.9
mask=255.255.0.0
add ip interface=ppp1 ipaddress=203.45.90.2
mask=255.255.255.0
add ip interface=eth0 ipaddress=172.73.1.2
mask=255.255.255.0
5.
Configure IGMP.
To enable IGMP on the router for multicast group management, enter the
command:
enable ip igmp
To enable IGMP on the interfaces that have potential multicast receivers (IP
hosts) connected to them, and the interfaces using DVMRP, enter the
commands:
enable ip igmp interface=eth0
enable ip igmp interface=ppp0
enable ip igmp interface=ppp1
6.
Configure DVMRP.
To enable DVMRP for multicast routing, enter the command:
enable dvmrp
Enable DVMRP on the interfaces that use DVMRP for multicast routing.
Setting the metrics on each of the interfaces influences the path cost and
therefore the traffic sent over the interface. (The higher the metric, the
