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

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

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(stack)cansupportupto24routinginterfaces.Eachint erfacecanbe
configuredfortheRIPand/orOSPFroutingprotocols.
