The range is 4 to 1800 seconds.min-ra-interval{interval}Enter the keywords min-ra-interval followed by the interval inseconds. The range is 3 to 1350 seconds.Defaults • Max RA interval: 600 seconds• Min RA interval: 200 secondsCommand Modes INTERFACEipv6 nd mtuConfigure an IPv6 neighbor discovery.C-Series, E-Series, S-SeriesSyntax ipv6 nd mtu numberParameters mtunumber Set the MTU advertisement value in Routing Prefix Advertisementpackets. The range is 1280 to 9234.Defaults noneCommand Modes INTERFACECommand History Version 8.3.1.0 IntroducedUsageInformationThe ip nd mtu command sets the value advertised to routers. It does not set the actualMTU rate. For example, if ip nd mtu is set to 1280, the interface still passes 1500-bytepackets.The mtu command sets the actual frame size passed and can be larger than the advertisedMTU. If the mtu setting is larger than the ip nd mtu command, an error message is sent, butthe configuration is accepted. The error message is: % Error: nd ra mtu isgreater than link mtu, link mtu will be used.1029
