Topic #: 1

In BGP, the AS_Path attribute records the numbers of all ASs that a route passes through from the local end to the destination in the vector order.
Which of the following statements is false about the attribute change during route transmission?

A. When advertising the route to an IBGP peer, the BGP speaker creates an empty AS_Path in the Update message. B. When advertising the route to an EBGP peer, the BGP speaker adds the local AS number to the end of the AS_Path. C. When advertising the route to an EBGP peer, the BGP speaker creates an AS_Path carrying the local AS number in the Update message. D. When advertising the route to an IBGP peer, the BGP speaker does not change the AS_Path attribute of the route.

Suggested Answer: A Vote an answer

OptionA is false. When advertising a route to an IBGP peer, theBGP speaker does not modifythe AS_Path. It simply advertises the routeas-is, preserving the AS_Path learned from EBGP.
Clarification of the options:
Bis correct: When a route is sent to an EBGP peer, the local AS is prepended to the AS_Path.
Cis correct: The AS_Path begins with the local AS when a new route is advertised to an EBGP neighbor.
Dis correct: IBGP doesnotmodify AS_Path when passing routes within the same AS.
Reference from Huawei HCIP-Datacom-Core Technology Study Guide:
"BGP speakers prepend their AS number to the AS_Path only when advertising to EBGP peers. IBGP peers do not alter the AS_Path." (Chapter: BGP Path Attributes - Section: AS_Path)
