When configuring IPv6 Static Routing, go to these sections for information you are
interested in:

Note:
The term “router” in this document refers to either a router in a generic sense or an
Ethernet switch running routing protocols.
1.1 Introduction to IPv6 Static Routing
Static routes are special routes that aremanually 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.
1.1.1 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.
1.1.2 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.

1.2 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.
1.2.1 Configuration prerequisites
zConfiguring parameters for the related interfaces
zConfiguring link layer attributes for the related interfaces
zEnabling IPv6 packet forwarding
zEnsuring that the neighboring nodes are IPv6 reachable

Note:
While configuring a static route, you can configure either the output interface or the
next-hop address depending on the situations:
zIf the output interface is a broadcast interface, or an NBMA interface, the next hop
address must be specified.
zIf the output interface is a point-to-point interface, you can specify either the output
interface or the next hop address, but not both.
1.3 Displaying and Maintaining IPv6 Static Routes

Note:
Using the undo ipv6 route-static command can delete asingle IPv6 static route, while
using the delete ipv6 static-routes all command deletes all IPv6 static routes
including the default route.
1.4 IPv6 Static Routing Configuration Example
I. Network requirements
With IPv6 static routes configured, all hosts and switches can interact with each other.
II. Network diagram
Figure 1-1 Network diagram for static routes (on switches)
III. Configuration procedure
1) Configure the IPv6 addresses of all VLAN interfaces (Omitted)
2) Configure IPv6 static routes.
# Configure the default IPv6 static route on SwitchA.
<SwitchA> system-view
[SwitchA] ipv6 route-static :: 0 4::2
# Configure two IPv6 static routes on Switch B.
<SwitchB> system-view
[SwitchB] ipv6 route-static 1:: 64 4::1

[SwitchB] ipv6 route-static 3:: 64 5::1
# Configure the default IPv6 static route on Switch C.
<SwitchC> system-view
[SwitchC] ipv6 route-static :: 0 5::2
3) Configure the IPv6 addresses of hosts and gateways.
Configure the IPv6 addresses of all the hosts based upon the network diagram,
configure the default gateway of HostA as 1::1, that of Host B as 2::1, and that of Host
C as 3::1.
4) Display configuration information
# Display the IPv6 routing table of SwitchA.
[SwitchA] display ipv6 routing-table
