The term “router” in this document refers to a router in a generic sense or a Layer 3 switch.

EA boards (such as LSQ1GP12EA and LSQ1TGX1EA) do not support IPv6 features.
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. Currently, IPv6 static routes do not support
VPN instance.
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.
