As shown in the figure, a company sets up an OSPF network. The links in the figure all form OSPF adjacencies, and all OSFP devices declare their own loopback addresses. One day SIR2 The two links of the S2AR1 suddenly failed, and in order to detect if the network was operating properly, the engineers performed a device status check, which is correct as described below

R5 can normally learn the loopback route to R2

R3 can not learn the loopback route to R2

R1 can normally learn the loopback route

R3 of R2 The loopback route of R2 can be learned normally

Question 393

The interface Serial0 of an existing router is in OSPF area 1, and the interface Serial0 is set to Silent interface. So what kind of impact will this setting have

OSPF establishes available adjacencies through this interface

OSPF does not add routes learned from the interface to the local routing table

OSPF does not establish any neighboring relationships through this interface D. OSPF receives routing updates from neighbors

Question 396

What kind of scenario can use AS-path-filter?( Multiple select).

A Filters routes received from BGP neighbors based on the AS PATH attribute carried by the route, such as the command peer X.x.x.x as path-filter import

The apply clause in Route policy

Filter routes sent to BGP neighbors based on the AS PATH attribute that the route carries. For example, the command peer x.x.x.x as path-filter export

The if-match clause in Route-policy

Question 397

In the following topology diagram,

R1 can be established between R2 and R3 fetches the Internet, RI and R2, R1 and R3 EGP connections, R2, R3 belong to the same AS The default routes are issued through BGP separately, requiring R2 to be preferred for traffic accessed by RI to the Internet, and the following practices can be achieved

R1 specifies that peer R3 sets the MED property to 150 in the import direction

R2 specifies that peer R1 is in export The direction setting local priority is 150

R2 specifies peer R1 in the export direction setting MED property to 150

R1 specifies the peer R2 sets the local priority in the import direction to 150

Question 398

The existing router HWl running BGP is configured with both IBGP neighbors and EBGP tenants. The following descriptions about IBGP Neighbors and EBGP Neighbors are correct?

The router will have an EBGP BGP neighbor from it must be connected directly, otherwise, IBGPMulti- hop must be configured

The router sends BGP updates learned from its EBGP neighbors to its other IBGP neighbors and EBGP neighbors

IBGP neighbors can establish neighbor relationships through the Loopback interface

The router sends BGP updates learned from its IBGP neighbors to its other IBGP neighbors and EPGP neighbors

EBGP neighbors must be directly connected, otherwise, EBGP-Multi-hop must be configured with
