Followingthefirstthreeinterfacesintheoutput,therewillbeanadditionalinterfaceforeachVLAN.The
nameofaninterfacewillbeeth0.nnwherennistheVLANnumbertowhichtheIPaddressisassigned.Note
thateventhoughtheinterfaceisshownaseth0,theIPaddresscanbereachedonlythroughinterfacesto
whichthatVLANhasbeenassigned.
4.4.7 Reviewthenewconfiguration.
TheconfigurationcreatedinthissectioncreatesthreedistinctinterfacesforuseonIBR.
a. eth0.1isthemanagementinterfaceonVLAN1(thedefaultVLANonIBR).VLAN1hasbeenassignedto
GigabitEthernetportge0andgiventheIPaddress192.168.128.101/16.
ThisinterfaceisisolatedfromtheotherinterfacesandcanbeusedtoaccesstheIBRandmanagethe
switchwithoutallowingmanagementtraffictotraversetheRFlink.BecauseVLAN1isassociatedonly
withge0andnotge3,VLAN1trafficwillnottransversethelink.
b. eth0.2isthedatainterfaceonVLAN2,whichhasbeenassignedtoGigabitEthernetportsge1,ge2,and
ge3.
TrafficonVLAN2canbesentacrosstheRFlinkandoutontothenetwork.Itallowsalluntaggedtraffic
andtraffictaggedwithVLANID2tobesenttothenetwork.
