Operation Manual – IPv6 RoutingH3C S7500E Series Ethernet Switches Chapter 1 IPv6 Static Routing Configuration1-1Chapter 1 IPv6 Static Routing ConfigurationNote:z The term “router” in this document refers to a Layer 3 switch running routingprotocols.z At present, the LSQ1GP12EA boards in the S7500E series do not support IPv6.1.1 Introduction to IPv6 Static RoutingStatic routes are special routes that are manually configured by network administrators.They work well in simple networks. Configuring and using them properly can improvethe performance of networks and guarantee enough bandwidth for importantapplications.However, static routes also have shortcomings: any topology changes could result inunavailable routes, requiring the network administrator to manually configure andmodify the static routes.1.1.1 Features of IPv6 Static RoutesSimilar to IPv4 static routes, IPv6 static routes work well in simple IPv6 networkenvironments.Their major difference lies in the destination and next hop addresses. IPv6 static routesuse IPv6 addresses whereas IPv4 static routes use IPv4 addresses.1.1.2 Default IPv6 RouteThe IPv6 static route that has the destination address configured as ::/0 (indicating aprefix length of 0) is the default IPv6 route. If the destination address of an IPv6 packetdoes not match any entry in the routing table, this default route will be used to forwardthe packet.1.2 Configuring an IPv6 Static RouteIn small IPv6 networks, IPv6 static routes can be used to forward packets. Incomparison to dynamic routes, it helps to save network bandwidth.
