The helper-role command configures the device to support the helper mode.
The undo helper-role command disables the helper mode on the device.
By default, the helper mode is disabled on the device.
helper-role [ { acl-name acl-name | acl-number acl-number | ip-prefix ip-prefix-name } | max-grace-period period | planned-only | lsa-checking-ignore ] *
undo helper-role [ { [ acl-name [ acl-name ] ] | [ acl-number [ acl-number ] ] | [ ip-prefix [ ip-prefix-name ] ] } | [ max-grace-period [ period ] ] | [ planned-only ] | [ lsa-checking-ignore ] ] *
| Parameter | Description | Value |
|---|---|---|
| acl-name acl-name |
Specifies the name of a named basic ACL. |
The value is a string of 1 to 64 case-sensitive characters without spaces. The value must start with a letter (a to z or A to Z, case sensitive). |
| acl-number acl-number |
Specifies the number of a basic ACL. |
The value is an integer that ranges from 2000 to 2999. |
| ip-prefix ip-prefix-name |
Specifies the name of an IP prefix list. |
The name is a string of 1 to 169 case-sensitive characters, with spaces not supported. When double quotation marks are used around the string, spaces are allowed in the string. |
| max-grace-period period |
Specifies the permitted maximum restart period. |
The value is an integer ranging from 1 to 1800, expressed in seconds. The default value is 120 seconds. |
| planned-only |
Indicates that devices support planned-GR only. By default, devices support planned-GR and unplanned-GR. |
- |
| lsa-checking-ignore |
Indicates that the strict check is not performed on LSAs. By default, devices perform strict check on received LSAs. |
- |
Usage Scenario
Devices cannot use the helper mode during the GR process.
When the rule (basic ACL6 view) command is used to configure a filtering rule for a named ACL, only the source address range that is specified in source and the time period that is specified in time-range take effect on the filtering rule.
