Configuring PIM Connectivity Between the Provider and PE Routers
To configure PIM on the main routing instance for
all provider and PE routers, include statements at the [edit protocols
pim] hierarchy level:
- Configure the interfaces between each provider router
and the PE routers by including the interface statement at
the [edit protocols pim] hierarchy level. On all PE routers,
enable PIM version 2 and sparse mode on interface lo0 of
the PE routers, either by configuring that specific interface or by
including the statement set version 2 mode sparse for interface all at the [edit protocols pim] hierarchy
level on a PE router.
- Configure PIM version 2 by including the version statement at the [edit protocols pim interface interface-name] hierarchy level.
- Configure sparse mode (the mode in which the PIM interfaces
operate) by including the mode statement at the [edit
protocols pim interface interface-name] hierarchy
level.
- Configure the RP address by including the static statement at the [edit protocols pim rp] hierarchy level.
In Figure 34, the provider router is the RP.
Figure 34 shows a multicast
configuration on the provider network.
