Question #14

The router passes two parallel cables and two EPE serial neighbors. What method do you use to implement the cable in two parallels?
Two EBGP of the connection? Two-way sharing of the neighbor load

A. Configure Loopback EBGP with the interface as the update source. AS IGP EBGP is the neighbor relationship. Each of the two neighbor rings that arrive at the home address is required.
Price path and need to use the command; "next-hop-local"

B. Use the command "ebgp-load-balance" at both ends

C. Configure the loopback EBGP with the interface as the update source. AS IGP EBGP is the neighbor relationship. Each neighbor ring that needs to arrive at the home loop address is required.
Equivalent path and need to use the command and ; "ebgp-max-hop "next-hop-local

D. Without any method, the traffic will be shared by different autonomous systems on the available roads, and the BGP dynamic chain will realize the inter-system load.

E. Use the interface to establish a relationship and configure Loopback EBGP EBGP Multi--hop, Loopback, IGP neighbor configuration interface as the update source for The equivalent load of the address is used to share the load between the implementations.
