prevent suboptimal

prevent loops

NEW QUESTION 73
Which of the following statements about 1S-IS (IPv6) is correct? (Multiple choice)

To support the processing and calculation of IPv6 routing, IS-IS added NLPID to 129 TLV

IS-IS working at the data link layer only needs to add a new TLV to support Pv6

To support the processing and calculation of IPv6 routes, IS-IS has added TLV232236

By default, IS-IS enables the multi-topology feature

TRUE

FALSE

NEW QUESTION 75
Regarding the description of the MPLS forwarding mechanism, which of the following is correct? (Multiple choice)

The system automatically assigns an ID to the upper-layer application that uses the tunnel, also known as Tunnel ID

When an IP packet enters the MRLS domain, the FIB table is the first to be checked

If the Tunnel ID value is not 0x0, and then enter the normal IP forwarding process

If the Tunnel ID value is 0x0, and then enter the MPLS forwarding process

NEW QUESTION 76

NEW QUESTION 81
. OSPFv2 is an IGP running on an IIPv4 network. OSPFV3 is an IGP running on an IPv6 network. Compared with OSPFv2, OSFv3 has similar LSA, but the function is slightly different. The following is the description of the LSA function of OSPFv3. Please drag the LSA to the correct LSA function column.

NEW QUESTION 82
In an operator’s MPLSVPN network, there are two devices PE1 and PE2 for MPLSVPN data forwarding. PE1 receives a private network route of 172.16.1.0/24 from the client, and converts it to a VPNv4 route on PE1 and assigns a label of 1027 Released to PE2. The outgoing label of the MPLS LSR-ID of PE2 reaching PE1 is 1025o When a client on PE2 accesses 172.16.1.0/24, the frame sent by PE2, the inner and outer labels should be a combination of the following 6 options?

outer layer label:1025:inner label:1027

outer layer label:1027:inner label:1027

Layer Label:1027:inner label:1025
