QUESTION: 93

The topology is as follows,R1 can access the Internet through R2 and R3, RI and R2, An EGP connection is established between R1 and R3. R2 and R3 belong to the same AS. They advertise default routes through BGP respectively. It is required that the traffic from R1 to access the Internet prefers R2. The following methods can be implemented:

R1 specifies that the peer R3 sets the MED attribute to 150 in the import direction
R2 specifies that peer R1 sets the local priority in the export direction to 150
R2 specifies that peer R1 sets the MED attribute to 150 in the export direction
R1 specifies that peer R2 sets the local priority to 150 in the import direction

Answer(s): A,D

Explanation:

It can be adjusted through local-preference and MED, and achieved by changing the priority of bgp routes flowing into the local routerThe purpose of controlling how data flows out of the AS. The larger the local-preference, the higher the priority, which controls how data enters the AS.
MEDSmaller is better.

QUESTION: 94

The existing router HW1 running BGP is configured with both IBGP neighbors and EBGP neighbors.
Below about IBGPneighbors and
EBGP neighbor description correct?

IBGP neighbors must be directly connected, otherwise, IBGP-Multi-hop must be configured
The router will send BGP updates learned from its EBGP neighbors to its other IBGP neighbors and EBGP neighbors
IBGP neighbors can pass LoopbackInterface establishes neighbor relationship
The router will send 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

Answer(s): B,C,E

Explanation:

Multi-hop configuration is required only when EBGP is not directly connected Routes learned by a router from IBGP neighbors can no longer be sent to its IBGP neighbors
