The additional metric is the metric (hop count) to be added to the original metric of a RIPng route. You can set additional metrics for received RIPng routes and those to be sent.
The system view is displayed.
The interface view is displayed.
The metric to be added to received routes is set.
Run any of the following commands as required:
Run ripng metricout { value | { acl6-number | acl6-name acl6-name } value1 } *
Run quit
Return to the system view.
Run acl ipv6 { name basic-acl6-name basic | [ number ] basic-acl6-number } [ match-order { config | auto } ]
The basic ACL view is displayed.
Run rule [ rule-id ] [ name rule-name ] { deny | permit } [ fragment | source { source-ipv6-address { prefix-length | source-wildcard } | source-ipv6-address/prefix-length | any } | time-range time-name | [ vpn-instance vpn-instance-name | vpn-instance-any ] ] *
A rule is configured for the basic ACL.
When the rule command is run to configure rules for a named ACL, only the source address range specified by source and the time period specified by time-range are valid as the rules.
If the action specified in an ACL rule is permit, a route that matches the rule will be received or advertised by the system.
If the action specified in an ACL rule is deny, a route that matches the rule will not be received or advertised by the system.
If a route has not matched any ACL rules, the route will not be received or advertised by the system.
If an ACL does not contain any rules, all routes matching the route-policy that references the ACL will not be received or advertised by the system.
In the configuration order, the system first matches a route with a rule that has a smaller number and then matches the route with a rule with a larger number. Routes can be filtered using a blacklist or a whitelist:
Route filtering using a blacklist: Configure a rule with a smaller number and specify the action deny in this rule to filter out the unwanted routes. Then, configure another rule with a larger number in the same ACL and specify the action permit in this rule to receive or advertise the other routes.
Route filtering using a whitelist: Configure a rule with a smaller number and specify the action permit in this rule to permit the routes to be received or advertised by the system. Then, configure another rule with a larger number in the same ACL and specify the action deny in this rule to filter out unwanted routes.
Based on the IP prefix:
Run ripng metricout { value | ipv6-prefix ipv6-prefix-name value1 } *
The configuration is submitted.
Run the ripng metricin command to set an additional metric for received RIPng routes. This command affects the metric of each received route in the routing table.
Run the ripng metricout command to set an additional metric for advertised RIPng routes. However, the metric of the route in the routing table remains unchanged.
If the metric plus the additional metric exceeds 16, 16 is used as the metric.
