Introduction to IPv6 Static Routing
Static routes are manually configured. 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.
Configuration prerequisites
l Configuring parameters for the related interfaces
l Configuring link layer attributes for the related interfaces
l Enabling IPv6 packet forwarding
l Ensuring that the neighboring nodes are IPv6 reachable
Configuring an IPv6 Static Route
Follow these steps to configure an IPv6 static route:
|
To do… |
Use the commands… |
Remarks |

|
Configure an IPv6 static route with the output interface being a broadcast interface |
ipv6 route-static ipv6-address prefix-length nexthop-address [ preference preference-value ] |
Required The default preference of IPv6 static routes is 60. |
While configuring a static route with a broadcast interface as its output interface, such as an Ethernet interface or a VLAN interface, you must specify the next hop address.
Displaying and Maintaining IPv6 Static Routes

To do… |
Use the command… |

display ipv6 routing-table |
Available in any view |
Using the undo ipv6 route-static command can delete a single IPv6 static route.
IPv6 Static Routing Configuration Example
Network requirements
The IP addresses and masks of the hosts and interfaces of the switches and the AP are shown in Figure 1-1. IPv6 static routes are required for interconnection between Host A and Host B.
Figure 1-1 Network diagram for IPv6 static route configuration
Configuration procedure
1) Configure the IPv6 addresses for all interfaces (omitted)
2) Configure IPv6 static routes.
# Configure a default IPv6 static route on Switch A.
<SwitchA> system-view
[SwitchA] ipv6
[SwitchA] ipv6 route-static :: 0 4::2
# Configure two IPv6 static routes on Switch B.
<SwitchB> system-view
[SwitchB] ipv6
[SwitchB] ipv6 route-static 1:: 64 4::1
[SwitchB] ipv6 route-static 3:: 64 3::1
# Configure a default IPv6 static route on the AP.
<AP> system-view
[AP] ipv6
[AP] ipv6 route-static :: 0 3::1
3) Configure gateways for hosts.
Configure the gateway of Host A as 1::1, and that of Host B as 3::3.
4) Verify the configuration.
# Ping Host B on Switch A.
<SwitchA> system-view
[SwitchA] ping ipv6 3::2
PING 3::2 : 56 data bytes, press CTRL_C to break
Reply from 3::2
bytes=56 Sequence=1 hop limit=254 time = 63 ms
Reply from 3::2
bytes=56 Sequence=2 hop limit=254 time = 62 ms
Reply from 3::2
bytes=56 Sequence=3 hop limit=254 time = 62 ms
Reply from 3::2
bytes=56 Sequence=4 hop limit=254 time = 63 ms
Reply from 3::2
bytes=56 Sequence=5 hop limit=254 time = 63 ms
--- 3::2 ping statistics ---
5 packet(s) transmitted
5 packet(s) received
0.00% packet loss
round-trip min/avg/max = 62/62/63 ms
