B.

E.

Router ID TLV #134

 

Correct Answer: ADE

Explanation:

TLV Name Description

1 Area Address Includes the Area Addresses to which the Intermediate System is conne
cted.

2 IIS Neighbors Includes all the IS-ISs running interfaces to which the router is connected.

8 Padding Primarily used in the IS-IS Hello (IIH) packets to detect the maximum transmission unit (MTU) inconsistencies. By default, IIH packets are padded to the fullest MTU of the interface.

10 Authentication The information that is used to authenticate the PDU, 22 TE IIS Neighbors Increases the maximum metric to three bytes (24 bits). Known as the Extended IS

Reachability TLV, this TLV addresses a TLV 2 metric limitation. TLV 2 has a maximum metric of 63, but only six out of eight bits are used.

128 IP Int. Reachability Provides all the known IP addresses that the given router knows about via one or more internally-originated interfaces. This information may appear multiple times.

129 Protocols Supported Carries the Network Layer Protocol Identifiers (NLPID) for Network Layer protocols that the IS (Intermediate System) is capable. It refers to the Data Protocols that are supported. For example, IPv4 NLPID value 0xCC, CLNS NLPID value 0x81, and/or IPv6 NLPID value 0x8E will be advertised in this NLPID TLV.

130 IP Ext. Address Provides all the known IP addresses that the given router knows about via one or more externally-originated interfaces. This information may appear multiple times.

132 IP Int. Address The IP interface address that is used to reach the next-hop address.

134 TE Router ID This is the Multi-Protocol Label Switching (MPLS) traffic engineering router ID.

135 TE IP Reachability Provides a 32 bit metric and adds a bit for the “up/down” resulting from the routeleaking of L2->L1. Known as the Extended IP Reachability TLV, this TLV addresses the issues with both TLV 128 and TLV 130.

137 Dynamic Hostname Identifies the symbolic name of the router originating the link-state packet (LSP).

10 and 133 TLV 10 should be used for Authentication; not the TLV 133. If TLV 133 is received, it is ignored on receipt, like any other unknown TLVs. TLV 10 should be accepted for authentication only.

 

 

QUESTION 58

Which statement about OSPF authentication is true?

 

A.

To enable OSPF authentication in a network, OSPF area 0 authentication must be enabled first.

B.

The payload of OSPFv3 packets contains no authentication information.

C.

OSPFv3 supports Advanced Encryption Standard

D.

OSPFv3 uses router ID as a key to encrypt OSPF hello packets.

E.

OSPF MD5 authentication uses TCP, and Plan Test authentication uses UDP.

 

Correct Answer: B

 

 

QUESTION 59

Which are correct descriptions and configurations of Anycast RP? (Choose three).

 

A.

In Anycast RP, two or more RPs are configured with the same IP address on loopback interfaces.

B.

Anycast RP provides redundancy and load-sharing capabilities.

C.

Routers with Anycast RP can be configured statically (loopback 1.1.1.1) with the command ip pim rpaddress 1.1.1.1

D.

Routers with Anycast RP can be configured statically (loopback 1.1.1.1) with the command ip rp-address pim 1.1.1.1

E.

Routers with Anycast RP can be configured statically (loopback 1.1.1.1) with the command ip anycast-rp pim 1.1.1.1
