Configuring IPv6 static routing
Introduction to IPv6 static routing
Static routes are manually configured. If a network's topology is simple, you only need to configure static
routes for the network to work correctly.
Static routes cannot adapt to network topology changes. If a fault or a topological change occurs in the
network, the network administrator has to modify the static routes manually.
Similar to IPv4 static routes, IPv6 static routes work well in simple IPv6 network environments.
IPv6 static routes features
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.
IPv6 default route
The IPv6 static route that has the destination address configured as ::/0 (indicating a prefix length of 0)
is the IPv6 default 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.
Before you configure an IPv6 static route, complete the following tasks:
• Configure parameters for the related interfaces.
• Configure link layer attributes for the related interfaces.
• Enable IPv6 packet forwarding.
• Make sure the neighboring nodes are IPv6 reachable.
To configure an IPv6 static route:
