apply extcommunity bandwidth

Function

The apply extcommunity bandwidth command sets the bandwidth extended community attribute for routes.

The undo apply extcommunity bandwidth command deletes the bandwidth extended community attribute.

By default, no bandwidth extended community attribute values are set for routes.

Format

apply extcommunity bandwidth { extCmntyString | none }

apply extcommunity bandwidth aggregate [ limit bandwidth-value ]

undo apply extcommunity bandwidth [ extCmntyString | none ]

undo apply extcommunity bandwidth aggregate [ limit bandwidth-value ]

Parameters

Parameter	Description	Value
extCmntyString	Specifies the bandwidth extended community attribute value.	The value of the bandwidth extended community attribute consists of the AS number and bandwidth value. The format is AS number:bandwidth value, for example, 1:100, in which the AS number ranges from 1 to 65535, and the bandwidth value ranges from 1 to 4294967295.
none	Clears the bandwidth extended community attribute of routes.	-
aggregate	Indicates the aggregated bandwidth extended community attribute.	-
limit	Indicates the maximum value of the aggregated bandwidth extended community attribute.	-
bandwidth-value	Specifies the aggregated bandwidth.	The value is an integer ranging from 1 to 4294967295, in kbit/s.

Usage Guidelines

Usage Scenario

After the apply extcommunity bandwidth command is run, routes advertised by the device carry the bandwidth extended community attribute, which is used to identify sites. Pay attention to the following points when running this command:

Run the route-policy command to enter the route-policy view.

A route-policy can consist of multiple nodes, and the relationship between nodes is OR. The system checks each node based on the node sequence number. The later node overwrites the previous node.

Example

# Add 1:1 to the bandwidth extended community attribute of routes.

<HUAWEI> system-view
[~HUAWEI] route-policy aaa permit node 1
[~HUAWEI-route-policy] apply extcommunity bandwidth 1:1

# Set the maximum value of the aggregated bandwidth extended community attribute to 100 kbit/s.

<HUAWEI> system-view
[~HUAWEI] route-policy aaa permit node 1
[~HUAWEI-route-policy] apply extcommunity bandwidth aggregate limit 100

# Clear the bandwidth extended community attribute of routes.

<HUAWEI> system-view
[~HUAWEI] route-policy aaa permit node 1
[~HUAWEI-route-policy] apply extcommunity bandwidth none
