Question 1

Which of the following about PIM messages for IPv6 multicast routing is FALSE?

Accepted Answer

Hello and Join/Prune messages typically use the link-local address of the outgoing interface as the source address, not the global unicast address.

Question 6

Which of the following is NOT required when configuring an MVPN with mLDP as its S-PMSI?

Accepted Answer

A range of multicast group addresses is not required for mLDP-based S-PMSI tunnels, as mLDP uses labels instead of multicast group addresses for signaling.

Question 7

Which of the following ranges is reserved for IPv6 SSM multicast addresses?

Accepted Answer

FF3X::/96 is reserved for IPv6 SSM multicast addresses.

Question 8

In Draft Rosen, a PE router encapsulates customer multicast packets into provider packets. What is the destination IP address of the provider packets sent on the I-PMSI?

Accepted Answer

The destination IP address of the provider packets sent on the I-PMSI is the multicast group address configured for the I-PMSI, as this is used to distribute the multicast traffic across the provider network.

Question 9

Which of the following is NOT an advantage of using P2MP LSP as P-tunnels that instantiate PMSIs?

Accepted Answer

P2MP LSP tunnels forward multicast traffic to all PEs in the path, not only to those with interested receivers, which can lead to inefficiencies.

Question 10

What is the DATA_DELAY_INTERVAL?

Accepted Answer

The DATA_DELAY_INTERVAL is the delay before the source PE switches traffic from the I-PMSI to the S-PMSI.

Question 11

The customer multicast network is running PIM SSM. The MVPN is using BGP A-D to distribute C-multicast routes. Which BGP route does a PE send to the core when it receives a PIM (S,G) Join from its CE?

Accepted Answer

When a PE receives a PIM (S,G) Join from its CE, it sends a Source Tree Join A-D route to the core. This route is used to signal the specific source and group information in the MVPN context.

Question 15

How do routers in the PIM domain learn the address of the elected BSR?

Accepted Answer

The elected BSR (Bootstrap Router) address is flooded through the network in a bootstrap message, allowing all routers in the PIM domain to learn about it.

Question 16

Question 18

Which of the following about the I-PMSI is TRUE?

Accepted Answer

The I-PMSI (Inclusive Provider Multicast Service Interface) is created and signaled by PIM (Protocol Independent Multicast) or BGP Auto Discovery in the context of Multicast VPNs (MVPNs).

Question 19

Which of the following conditions triggers the S-PMSI construction in Draft Rosen?

Accepted Answer

The S-PMSI (Selective Provider Multicast Service Interface) is constructed when multicast data exceeds a certain threshold set on the ingress PE (Provider Edge).

Question 20

Which of the following describes how customer multicast routing information is distributed in NG MVPN?

Accepted Answer

In NG MVPN (Next Generation Multicast VPN), customer multicast routing information can be distributed using either PIM (Protocol Independent Multicast) or MP-BGP (Multiprotocol BGP), allowing for flexibility in the network design.
