378in multicast by default, packets are only broadcasted when v2-broadcast is set on theinterface.15.3.2.2.11 ip rip workCommand: ip rip workno ip rip workFunction: Configure the interface to run RIP or not; the “no ip rip work” commanddisables RIP packet sending/receiving on the interface.Default: After enabling RIP, RIP is enabled on the ports by default.Command mode: Interface ModeUsage Guide: This command is equal to “no ip rip send version & no ip rip receiveversion” in function, the latter two commands control the receiving and sending of RIPpacket on the interface, the former equals the total of the latter two commands.Related command: no ip rip send version 、no ip rip receive version15.3.2.2.12 ip split-horizonCommand: ip split-horizonno ip split-horizonFunction: Set to enable split horizon; the “no ip split-horizon” command disables splithorizon.Default: split horizon is enabled by default.Command mode: Interface ModeUsage Guide: Set split horizon to prevent routing loops, i.e. prevent layer3 switch frombroadcasting the route leaned from the same interface.Example: Disable split horizon for interface vlan1.Switch(Config)#interface vlan1Switch(Config-If-Vlan1)#no ip split-horizon15.3.2.2.13 redistributeCommand: redistribute { static | ospf | bgp} [ metric <value> ]no redistribute { static | ospf | bgp }Function: Introduce routes of the other protocols into RIP; the “no redistribute { static |ospf | bgp }” command cancels the introduction.Parameter: static specifies static routes to be introduced; ospf for OSPF routes; bgpfor BGP routes; <value> stands for the route metric in introducing the routes,ranging from 1 to 16.
