1.1 IPv6 Static Routing Configuration Commands
1.1.1 delete ipv6 static-routes all
Syntax
delete ipv6 static-routes all
View
System view
Parameter
None
Description
Use the delete ipv6 static-routes all command to delete all static routes including the default route.
When using this command, you will be prompted whether to continue the deletion and only after you have confirmed the deletion will the static routes be deleted.
Related command: display ipv6 routing-table, ipv6 route-static.
Example
# Delete all IPv6 static routes.
<Sysname> system-view
[Sysname] delete ipv6 static-routes all
This will erase all ipv6 static routes and their configurations, you must reconfigure all static routes
Are you sure?[Y/N]Y
1.1.2 ipv6 route-static
Syntax
ipv6 route-static ipv6-address prefix-length [ interface-type interface-number ] nexthop-address [ preference preference-value ]
undo ipv6 route-static ipv6-address prefix-length [ interface-type interface-number ] [ nexthop-address ] [ preference preference-value ]
View
System view
Parameter
ipv6-address prefix-length: IPv6 address and prefix length.
interface-type interface-number: The interface type and interface number of the output interface.
nexthop-address: Next hop IPv6 address.
preference-value: Route preference value, in the range of 1 to 255. Defaults to 60.
Description
Use the ipv6 route-static command to configure an IPv6 static route.
Use the undo ipv6 route-static command to remove an IPv6 static route.
An IPv6 static route that has the destination address configured as “::/0” (a prefix length of 0) is the default IPv6 route. If the destination address of an IPv6 packet does not match any entries in the routing table, this default route will be used to forward the packet.
Related command: display ipv6 routing-table, delete ipv6 static-routes all.
Example
# Configure a static IPv6 route, with the destination address being 1:1:2::/24 and next hop being 1:1:3::1.
<Sysname> system-view
[Sysname] ipv6 route-static 1:1:2:: 24 1:1:3::1

2.1.19 timers
Syntax
timers { garbage-collect garbage-collect-value | suppress suppress-value | timeout timeout-value | update update-value }*
undo timers { garbage-collect | suppress | timeout | update }*
View
RIPng view
Parameter
garbage-collect-value: Interval of the garbage-collect timer in seconds, in the range of 1 to 86400.
suppress-value: Interval of the suppress timer in seconds, in the range of 0 to 86400.
timeout-value: Interval of the timeout timer in seconds, in the range of 1 to 86400.
update-value: Interval of the update timer in seconds, in the range of 1 to 86400.
Description
Use the timers command to configure RIPng timers.
Use the undo timers command to restore the default.
By default, the interval of the garbage-collect timer is 240 seconds, that of the suppress timer 120 seconds, that of the timeout timer 180 seconds, and that of the update timer 30 seconds.
RIPng is controlled by the above four timers.
l The update timer defines the interval between update messages.
l The timeout timer defines the route aging time. If no update message related to a route is received within the aging time, the metric of the route is set to 16 in the routing table.
l The suppress timer defines how long a RIPng route stays in the suppressed state. When the metric of a route is 16, the route enters the suppressed state. In the suppressed state, only routes which come from the same neighbor and whose metric is less than 16 will be received by the router to replace unreachable routes.
l The garbage-collect timer defines the interval from when the metric of a route becomes 16 to when it is deleted from the routing table. During the garbage-collect timer length, RIPng advertises the route with the routing metric set to 16. If no update message is announced for that route before the garbage-collect timer expires, the route will completely be deleted from the routing table.
Note that:
l You are not recommended to change the default values of these timers under normal circumstances.
l The lengths of these timers must be kept consistent on all routers and access servers in the network
Example
# Configure the update, timeout, suppress, and garbage-collect timers as 5s, 15s, 15s and 30s.
<Sysname> system-view
[Sysname] ripng 100
[Sysname-ripng-100] timers update 5
[Sysname-ripng-100] timers timeout 15
[Sysname-ripng-100] timers suppress 15
[Sysname-ripng-100] timers garbage-collect 30

Syntax
ip ipv6-prefix ipv6-prefix-name [ index index-number ] { deny | permit } ipv6-address prefix-length [ greater-equal min-prefix-length ] [ less-equal max-prefix-length ]
undo ip ipv6-prefix ipv6-prefix-name [ index index-number ]
View
System view
Parameter
ipv6-prefix-name: IPv6 prefix list name, a string of 1 to 19 characters, for uniquely specifying an IPv6 prefix list.
index-number: Index number, in the range 1 to 65535, for uniquely specifying an IPv6 prefix list item. The item with smaller index-number will be tested first.
permit: Specifies the matching mode for the IPv6 prefix list as permit, that is, when a route to be filtered is in the range of the IPv6 prefix list, the route passes the IPv6 prefix list without needing to enter the next item for testing. If the route to be filtered is not in the prefix range, it will enter the next item test.
deny: Specifies the matching mode for the IPv6 prefix list as deny, that is, when a route to be filtered is in the IPv6 prefix list range, the route neither passes the filter nor enters the next node for testing. If not in the range, the route will enter the next item test.
ipv6-address prefix-length: Specifies an IPv6 prefix and prefix length, with prefix-length in the range 0 to 128. When specified as :: 0, it matches the default route.
min-prefix-length, max-prefix-length: Specifies the range of IPv6 prefix if IPv6 address and prefix length are matched. greater-equal means “greater than or equal to” and less-equal means “less than or equal to”. The range relation is mask-length <= min-mask-length <= max-mask-length <= 32. If only min-prefix-length is specified, the prefix length range is [ min-prefix-length, 128 ]. If only max-prefix-length is specified, the prefix length range is [ prefix-length, max-prefix-length ]. If both min-prefix-length and max-prefix-length are specified, the prefix length range is [ min-prefix-length, max-prefix-length ].
Description
Use the ip ipv6-prefix command to configure an IPv6 prefix list item.
Use the undo ip ipv6-prefix command to remove an IPv6 prefix list or an item.
No IPv6 prefix list is configured by default.
The IPv6 address prefix list is used to filter IPv6 addresses. It may have multiple items, each of which specifies a range of IPv6 prefix. The filtering relation among items is logic OR, namely, it requires passing an item to pass the prefix list.
The IPv6 prefix range is determined by prefix-length and [ min-prefix-length, max-prefix-length ]. If both mask-length and [ min-mask-length, max-mask-length ] are specified, then the IPv6 addresses must satisfy both of them.
If ipv6-address prefix-length is specified as :: 0, then only the default routes will be matched.
If you want to match all the routes, configure it as :: 0 less-equal 128.
Example
# Let pass the IPv6 addresses with mask length between 32 bits and 64 bits.
<Sysname> system-view
[Sysname] ip ipv6-prefix abc permit :: 0 greater-equal 32 less-equal 64
# Refuse to let pass the IPv6 addresses with prefix as 3FFE:D00::/32, prefix length greater than or equal to 32 bits.
<Sysname> system-view
[Sysname] ip ipv6-prefix abc deny 3FEE:D00:: 32 less-equal 128

Description
Use the reset ip ipv6-prefix command to clear the statistics of the specified IPv6 prefix list. If no name is specified, the statistics of all IPv6 prefix lists will be cleared.
Example
# Specifies to delete statistics of the specified IPv6 prefix list.
<Sysname> reset ip ipv6-prefix abc
3.1.13 route-policy
Syntax
route-policy route-policy-name { permit | deny } node node-number
undo route-policy route-policy-name [ node node-number ]
View
System view
Parameter
route-policy-name: Route-policy name, a string of 1 to 19 characters for uniquely identifying a route-policy.
permit: Specifies the matching mode of the route policy node as permit. If a route satisfies all the if-match clauses, it is allowed to pass the filtering of the node and then executed with the apply clauses of the node. If a route fails to satisfy the if-match clauses of the node, it is matched by the next node of the route-policy.
deny: Specifies the matching mode of the route-policy node as deny. If a route satisfies all the if-match clauses, it is denied to pass the filtering of the node and is not matched to the next node.
node node-number: Routing policy node, in the range 0 to 65535. The node with a smaller node-number will be tested first when the routing policy is used for filtering routing information.
Description
Use the route-policy command to create a routing policy and enter its view.
Use the undo route-policy command to remove a routing policy.
No routing policy is created by default.
A route-policy is used for routing information filtering or policy routing. It contains several nodes and a node comprises some if-match and apply clauses. The if-match clauses define the matching rules of the node and the apply clauses define the actions performed after a packet passes the filtering of the node. The relation among the if-match clauses of a node is logic AND, namely all the if-match clauses must be satisfied. The filter relation among different route-policy nodes is logic OR, namely it requires passing any one node to pass the route-policy.
Related command: if-match interface,if-match ipv6,if-match cost,if-match tag,apply ipv6 next-hop,apply cost,and apply tag.
Example
# Configure routing policy 1 with node as 10 and matching mode as permit, and then enter routing policy view.
