How to Configure the Multicast
Time-to-Live Property
Use the following procedure to reset the net.slp.multicastTTL property.
- Become an administrator.
For more information, see Using Your Assigned Administrative Rights in Securing Users and Processes in Oracle Solaris 11.2
.
- Stop slpd and
all SLP activity on the host.
# svcadm disable network/slp
-
Back up the default /etc/inet/slp.conf file before you change the
configuration settings.
- Change the net.slp.multicastTTL property in the slpd.conf file:
net.slp.multicastTTL=value
- value
A positive integer less than or equal to 255 that
defines the multicast TTL
Note - You can reduce the range of multicast propagation
by reducing the TTL value. If the TTL value is 1, then the packet
is restricted to the subnet. If the value is 32, the packet is restricted
to the site. Unfortunately, the term
site is
not defined by RFC 1075, where multicast TTLs are discussed. Values
above 32 refer to theoretical routing on the Internet and should not
be used. Values below 32 can be used to restrict multicast to a set
of accessible subnets, if the routers are properly configured with
TTLs.
- Save your changes and close the
file.
- Restart slpd to
activate your changes.
# svcadm enable network/slp
