Hi Berisdav,
Check out the section in the Manuals on multicast scoping:
JunOS 5.0 Configuration Guide Multicast section 4: Multicast Scoping
Quote "Multicast scoping is a technique that can be used to limit multicast
traffic by configuring an administratively defined topological region.
Major objectives of scoping are to relieve stress on scarce resources, such
as bandwidth, and to improve privacy or scaling properties"
Config example.
[edit]
routing-options {
multicast {
scope internal_announce {
prefix 224.0.1.39/32;
interface so-x/y/z;
}
scope internal_discovery {
prefix 224.0.1.40/32;
interface so-x/y/z;
}
}
}
This has the same effect as the configuration below
Hope this helps
Gary Tate
