Figure 13: Multicast VPNs
To better understand the example, keep the following in mind:
■
Lp is a loopback interface in the parent router. This address is the loopback
interface used as the BGP peer address of the provider edge router (PE). Its
address is advertised in the provider address space.
■
Tv is the MTI in the VRF. This interface is typically configured as a PIM
sparse-mode interface (though you can configure it for dense-mode or
sparse-dense-mode). Any packets that originate in the VRF are sent using the
address of this interface as the source address. You must set this interface address
to be identical to loopback interface of the parent router (Lp).
CAUTION: Defining the Tv interface with an address other than the loopback interface
of the parent router might restrict operation with non-Juniper Networks routers.
■
Tp is an unnumbered IP interface that is tied to the loopback interface of the
provider edge router (PE).
To configure the example, use the following general procedures:
NOTE: This example provides general information for configuring a simple Multicast
VPN network. For detailed information about creating GRE tunnels, see Configuring
IP Tunnels in the JUNOSe IP Services Configuration Guide . For detailed information
about PIM sparse-mode configuration, see “PIM Sparse Mode” on page 82.
