Routerglobalconfigurationmode:C2(su)‐>router(Config)#
Usage
Thiscommandenablesinterfaceconfigurationmodefromglobalconfigurationmode,and,ifthe
interfacehasnotpreviouslybeencreated,thiscommandcreatesanewroutinginterface.For
detailsonconfigurationmodessupportedbytheSecureStackC2deviceandtheiruses,referto

detailsoncreatingVLANsandconfiguringthemforIP,referto“EnablingRouterConfiguration

Enablinginterfaceconfigurationmodeisrequiredforcompletinginterface‐specificconfiguration
tasks.Foranexampleofhowthesecommandsareused,referto“Pre‐RoutingConfiguration
Tasks”onpage 15‐1.
Aloopbackinterfaceisalways
expectedtobeup.Thisinterfacecanprovidethesourceaddressfor
sentpacketsandcanreceivebothlocalandremotepackets.Theloopbackinterfaceistypically
usedbyroutingprotocols.IfRADIUSisconfiguredwithnohostIPaddressonthedevice,itwill
usetheloopbackinterface0IP
address(ifithasbeenconfigured)asitssourcefortheNAS‐IP
attribute.
EachSecureStackC2systemcansupportupto24routinginterfaces.Eachinterfacecanbe
configuredfortheRIPand/orOSPFroutingprotocols.
Examples
Thisexampleshowshowtoenterconfiguration modeforVLAN1:
C2(su)->router#configure
C2(su)->router(Config)#interface vlan 1
C2(su)->router(Config-if(Vlan 1))#
Thisexampleshowshowtoenterconfiguration modeforloopback1:
C2(su)->router#configure
C2(su)->router(Config)#interface loopback 1
C2(su)->router(Config-if(Lpbk 1))#
vlanvlan‐id SpecifiesthenumberoftheVLANinterfacetobeconfiguredforrouting.
ThisinterfacemustbeconfiguredforIProutingasdescribedin“Pre‐
RoutingConfigurationTasks”onpage 15‐1.
loopbackloop‐id Specifiesthenumberoftheloopbackinterfacetobeconfiguredforrouting.
Thevalueof
loop‐idcanrangefrom0to7.
