ARP entries are automatically refreshed for the belowscenarios:• When an ARP request or gratuitous ARP is seen from an IP host• If traffic is alive for this ARP then around the last 60 seconds of its timeout ARP will berefreshed. This ARP refresh will not occur if arp-timeout is configured between 1 and 90If the arp-timeout value is set to 0 seconds, ARP aging is disabled.The no form of this command restores arp-timeout to the default value.Default 14400 secondsParameters seconds — The minimum number of seconds a learned ARP entry will be stored in the ARPtable, expressed as a decimal integer. A value of zero specifies that the timer is inoperativeand learned ARP entries will not be aged.Values: 0 — 65535Item DescriptionSyntax bfd transmit-interval [receive receive-interval] [multiplier multiplierno bfdContext configure>service>ies>interfaceDescription This command specifies the bidirectional forwarding detection (BFD) parameters for theassociated IP interface. If no parameters are defined the default values are used.The multiplier specifies the number of consecutive BFD messages that must be missed fromthe peer before the BFD session state is changed to down and the upper level protocols(OSPF, IS-IS, BGP or PIM) is notified of the fault.The no form of the command removes BFD from the router interface.Default no bfd(1 of 2)
