Example: Creating a Named Scope for Multicast Scoping
This example configures multicast scoping with the scope statement, creating four scopes: local, organization, engineering, and marketing.
If you have a Tunnel Physical Interface Card (PIC) in your router and you configure a tunnel interface to use IP-IP encapsulation, you can configure the local scope. For more information about configuring tunnel interfaces, see the Junos Network Interfaces Configuration Guide.
Configure the organization scope on an IP-IP encapsulation tunnel interface and a SONET/SDH interface. Configure the engineering and marketing scopes on an IP-IP encapsulation tunnel interface and two SONET/SDH interfaces. The Junos OS can scope any user-configurable IPv6 or IPv4 group.
To verify that group scoping is in effect, issue the show multicast scope command:
user@host> show multicast scopeResolve
Scope nameGroup prefixInterfaceRejects
