IPV6 STATIC ROUTING
CONFIGURATION
n
The term “router” in this document refers to a Layer 3 switch running routing
protocols.
Introduction to IPv6
Static Routing
Static routes are special routes that are manually configured by network
administrators. They work well in simple networks. Configuring and using them
properly can improve the performance of networks and guarantee enough
bandwidth for important applications.
However, static routes also have shortcomings: any topology changes could result
in unavailable routes, requiring the network administrator to manually configure
and modify the static routes.
Features of IPv6 Static
Routes
Similar to IPv4 static routes, IPv6 static routes work well in simple IPv6 network
environments.
Their major difference lies in the destination and next hop addresses. IPv6 static
routes use IPv6 addresses whereas IPv4 static routes use IPv4 addresses.
Default IPv6 Route The IPv6 static route that has the destination address configured as ::/0 (indicating
a prefix length of 0) is the default IPv6 route. If the destination address of an IPv6
packet does not match any entry in the routing table, this default route will be
used to forward the packet.
Configuring an IPv6
Static Route
In small IPv6 networks, IPv6 static routes can be used to forward packets. In
comparison to dynamic routes, it helps to save network bandwidth.
