Question 54

The following statement about isis protocol LSP messages is correct

The isP rapid diffusion feature, which first diffuses out LSPs that are smaller than a specified number , speeding up the synchronization process of LSDB

By configuring an LSP-generated smart timer, the timer automatically adjusts the delay time based on the frequency at which the routing information changes

As link status information increases, the packet length of the LSP can be increased so that each ISP can carry more information.

Reducing the minimum interval at which LSPs are sent per port can speed up the diffusion of LSPs.

Router RI and Router R2 run BGP. Both routers are in the AS65234 The route for router R2 exists in the BGP routing table of the router RI, but not in the IP routing table of the router RI . So what causes the problem to occur? (Single Choice

Questions).

Synchronization is turned off

The B. BGP neighbor relationship is Down

Router R1 does not enable BGP Multi-hop

Routing is not optimal

Question 56

Regarding the OSPFv3 protocol, what is the error described below?

Under the sukugan of a shared router, each OSPFv3 process runs independently

Multiple instances can be run in the same OSPFv3 under the same interface

Can support running multiple instances on a single link

OSPFv3 message header will contain instance IDFu Duan flogging

Inter-AreaPrefix-SA's LinkStatelD contains the prefix

Router-LSA and Network-LSA does not contain routing information

When the Intra-AreaPrefixLSA's ReferencedLinkStateType-2, referencedLinkStatelD contains the interface to DR ID

Inter-AreaPrefirLSA also contains LinkLocal information file

Question 60

There is an existing router interface serial 0 in OSPF area 1 , well will interface Serial 0 is set to silent interface. So what is the impact of this setting?

OSPF establishes usable adjacencies through this junction

OSPF does not join the routes learned from the connector to the local routing table

OSPF does not establish any adjacency relationships through the junction

OSPF receives a route update answer from the neighbor.
