Question 372

Which of the following options is described correctly for the assertion mechanism?( Radio).

Winner's election process does not make IP address size a condition of the election

In the assertion mechanism, the winner is responsible for forwarding multicast data to the broadcast segment

The assertion mechanism is used for the election of DR

In the assertion mechanism, the loser will shut down the interface with the broadcast network necklace

Question 373

The BSR/RP mechanism described below describes the correct determination ?( Multiple choice questions).

There can be multiple C-BSRs in the

PIM-SM domain, but only one BSR can be elected.

BSR collects C-RP information by receiving packets of C-RP

BSR advertises BSR and C-RP information to all routers in the PIM-SM domain via flood bootstrap messages

A C-BSR can also collect C-RP information by receiving C-RP packets

Question 374

The following description of LDP reliability is incorrectly ?( Radio).

LGP GR takes advantage of the high difference between the LS forwarding plane and the control plane to realize that the device forwards without interruption when the protocol is restarted or the master-standby is reversed

Manually configured LDP FRR policies default to 32-bit backup routes that trigger LDP to establish backup LSPs

LLDPFRR also allows LSPs to be generated for tag mappings from non-optimal next hops, and as a live LSP backup, supervising forwarding table entries

LDP and IGP linkage, the need for IGP has been routed to release, to ensure that LDP and LGP path consistent

Question 375

Regarding the LDP protocol session establishment process, the description is correct?

When both parties receive a keepalive message from the peer, the LDP session is successfully established

Hello messages discovered by LDP neighbors use TCP messages with a destination address of multicast address 224002

After the TCP connection is successfully established, the active party sends an initialization message to negotiate the relevant parameters of the LDP session,

The party with the larger transmission address initiates the establishment of a TCP connection as the active party

Question 377

LDP and IGP linkage refers to the release of IGP and TD routes to ensure that LDP and IGP linkage complete network efficiency, so that KGP and LDP maintains a consistent path, minimizing traffic loss, thereby improving the reliability of the entire network.

True

False

Question 378

Regarding the MPLS handling mode of TTL, the following description is correct?

Pipe mode. When an IP message passes through an MPLS network, the IPTTL minus l at the entry point is mapped to the MPLS TTL field

MPLS tags in the TTL, which mean the same as the TTL domain in the IP header. TTL prevents mpLS networks from creating routing loops

In Unifor mode, when an IP message passes through an MPLS network, the inbound IPTTL is minus

The MPLSTTL field is a fixed value

In MMLSVPI, if you need to hide the structure of the MPLS backbone network, you can use the Uniform mode on Ingress for private network messages
