In t'is packet tracer activit+, I oserve$ roa$cast tra%%ic in a VLAN Implementation.

I ping %rom PC1 to PC. T'e ping %romPC1 %ails eca(sePC1never receives an A)P

receives an A)P repl+. A%ter t'at, I oserve$ #roa$casts Tra%%ic &it'o(t VLANs. I

Concl(sion"A VLAN tr(nk, or tr(nk, is a point-to-point link et&een t&o net&ork $evices t'at carries

more t'an one VLAN. In normal operation, &'en a s&itc' receives a roa$cast %rame on

one o% its ports, it %or&ar$s t'e %rame o(t all ot'er ports ecept t'e port &'ere t'e
