(January 2001 expiration)
Before You Begin
You can configure multicast on IPv4 and IPv6 interfaces.
For information about configuring IP interfaces, see
Configuring IP
in the
JUNOSe IP,
IPv6, and IGP Configuration Guide
. For information about configuring IPv6 interfaces,
see
Configuring IPv6
in
JUNOSe IP, IPv6, and IGP Configuration Guide
.
For information about configuring multicast on IPv4 interfaces, see “Configuring
IPv4 Multicast” on page 3.
Configuring the Switching Fabric Bandwidth
By default, the switch fabric for the ERX1440, ERX310, E120, and E320 Broadband
Services Routers uses a bandwidth weighting ratio of 15:2 for multicast-to-unicast
weighted round robin (WRR). In the absence of strict-priority traffic, and when both
unicast and multicast traffic compete for switch fabric bandwidth, the switch fabric
allocates 15/17ths of the available bandwidth to multicast traffic and 2/17ths of the
available bandwidth to unicast traffic.
You can use the
fabric weights
command to change the ratio for multicast to unicast
traffic on the router switch fabric. For more information about the
fabric weights
command, see
Managing the System
in the
JUNOSe System Basics Configuration Guide
.
Enabling IPv6 Multicast
In this implementation, IPv6 multicast works on VRs. By default, IPv6 multicast is
disabled on a VR. To enable IPv6 multicast on a VR, access the context for a VR, and
then issue the
ipv6 multicast-routing
command.
ipv6 multicast-routing
■
Use to enable IPv6 multicast routing on the VR.
■
By default, IPv6 multicast is disabled on the VR. In the disabled state, all multicast
protocols are disabled, and the VR forwards no multicast packets.
■
Example
host1(config)#
ipv6 multicast-routing
■
Use the
no
version to disable IPv6 multicast routing on the VR (the default).
■
See ipv6 multicast-routing.
