Multicast Routing

What distinction must an engineer account for when deploying inter-domain and intra-domain multicast routing on a network?

  • A Intra-domain routing is dependent on the RP router within the same SP network, but inter-domain routing reduces the dependency on the other SP network.
  • B Intra-domain routing allows the service provider to control incoming and outgoing multicast data streams on its network, but inter-domain routing limits the service provider's control.
  • C Inter-domain routing supports policy routing to connect different multicast domains using PIM-SM, but intra-domain routing supports policy routing using PIM-SM only within a single domain.
  • D Intra-domain routing uses the PIM and MBGP protocols for multicast routing, but inter-domain routing must use PIM-SSM or MSDP.
Explanation

Within a PIM-SM domain, multicast operation depends on that domain’s RP. Inter-domain multicast can use MSDP to connect PIM-SM domains while each service provider maintains an independent RP, reducing dependence on other service-provider networks. MBGP supplies policy-based interdomain multicast routing when required.
