Konfiguration af Router - Trunk
Når der skal anvendes en TRUNK til en Router (Router-on-a-stick) skal der laves sub-interfaces til de forskellige VLAN der anvendes.
Trunkprotokollen IEEE 802.1Q
Trunkprotokollen 802.1Q til daglig kaldet DOT-one-Q, bliver pakkerne taggede (mærket) med fire ekstra Bytes der indsættes i Ethernet rammen. Se tegning herunder.
Der skal konfigureres et subinterface for hvert VLAN der anvendes.
Native VLAN
Der er et VLAN i 802.1Q protokollen der ikke tagges - altså mærkes. Dette VLAN kaldes Native VLAN, og er som standard VLAN 1. Se konfigurationseksempel herunder.
