Router R1, in ASN 11, learns a BGP route from BGP peer R22 in ASN 22. R1 and then uses
BGP to advertise the route to R2, also in ASN 11. What ASNs would you see in the BGP
table on R2 for this route?

A.
22

B.
11

C.
1

D.
None

Explanation:
The router in ASN 22, R22, advertises the BGP update with (at least) 22 in the AS_Path
Path Attribute (PA). When R1 advertises the route to R2, also in ASN 11, R1 does not add
an ASN. As a result, R2’s AS_Path has at least ASN 22 and not ASN 11.
