Multicast VPN Design for CCIE Service Provider

1. Which BGP community is typically used in mVPN to signal whether a PE router supports a specific mVPN technology?

Target Extended Community

MVPN Extended Community

Route Target

Origin AS

2. What is the key difference between Rosen Draft and NG-mVPN in terms of route advertisement?

Rosen uses unicast routes; NG uses multicast routes

Rosen uses MDT routes; NG uses BGP MVPN routes and optional data MDTs

Rosen requires OSPF; NG requires IS-IS

Rosen uses IGP only; NG uses BGP only

3. Which configuration element ensures that multicast traffic from different VPN customers does not leak into other VPNs?

VRF configuration

Route target filtering

Multicast boundary ACLs and VRF isolation

BGP multipath

4. For a college-level mVPN design, when would you choose PIM-SM over Source-Specific Multicast (SSM)?

When receivers know the source address

When receivers discover sources dynamically through RP

When bandwidth is limited

When convergence time is critical

5. In an mVPN design, what does the (C-S, C-G) tuple represent?

Customer Source and Customer Group (multicast source and group)

Core Segment and Gateway identifier

Carrier Service and Global routing

Conditional Source and Group filter

6. In NG-mVPN with BIER (Bit Index Explicit Replication), what is the primary benefit?

Eliminates the need for PIM

Reduces state in core routers and simplifies multicast forwarding

Increases multicast group limit to 1 million

Requires no BGP configuration

7. True or False: In NG-mVPN, customer multicast streams can use provider-based P2MP trees without requiring default MDT tunnels.

True

False

8. In a Rosen Draft mVPN, what does MDT stand for?

Multicast Distribution Tree

Multicast Delivery Tunnel

Multicast Data Tunnel

Multi-Domain Transmission

9. Which protocol is commonly used to carry multicast traffic through the service provider backbone in mVPN?

OSPF

IS-IS

MPLS multicast (P2MP LSP)

EIGRP

10. What is the primary purpose of a Route Distinguisher (RD) in mVPN?

To identify the VPN customer

To make customer multicast routes unique across the MPLS domain

To encrypt multicast traffic

To reduce BGP convergence time

11. Which of the following best describes a C-multicast route in mVPN?

A route learned from the provider's core routers

A multicast route from a customer's source to receivers

A backup route used during convergence

A route maintained by the PE router only

12. What is the primary advantage of using PIM-SM over PIM-DM in service provider mVPN designs?

Lower bandwidth consumption

Simpler configuration

Better scalability for sparse multicast groups

Faster convergence time

13. Which mVPN architecture uses a single default multicast tree to carry all customer multicast traffic?

Rosen Draft (MDT)

Next-Generation mVPN (NG-mVPN)

Source-Specific mVPN (SSMVPN)

Segment Routing mVPN

14. Which mVPN protocol mode requires customers to have PIM enabled on their CE-PE link?

BGP-only mode

Native PIM mode

Encapsulation mode

Overlay mode

15. In NG-mVPN, what BGP address family is used to advertise multicast routes?

IPv4 Multicast (MAFT)

MVPN SAFI 129

Multicast VPN SAFI 5

Provider Multicast Service SAFI 3

Submit

17. True or False: Rosen Draft mVPN requires all PE routers to maintain state for every customer multicast group.

True

False

Submit

19. True or False: Segment Routing (SR) can be used to optimize P2MP tree creation in mVPN without requiring RSVP-TE.

True

False

Submit
