Configure IP Prefix List on Devices

efa policy prefix-list create ?
Flags:
      --type string          Type of prefix-list. Valid types are ipv4
      --name string          Name of Prefix list
      --rule stringArray     Rule in format seq[seq-num],action[permit/deny],prefix[IPv4 prefix],ge[prefix-len],le[prefix-len]. Example: seq[5],action[permit],prefix[10.0.0.0/8],ge[10],le[24]

Following is an example of IPv4 prefix list create:

efa policy prefix-list create –-name prefix_v4 –-type ipv4 –-rule seq[5],action[permit],prefix[10.0.0.0/8],ge[16]

You can also use this command to add or remove rules.

efa policy prefix-list update ?
Flags:
      --type string      Type of prefix-list. Valid types are ipv4
      --name string      Name of Prefix list
      --operation string Valid options are add-rule, remove-rule, add-device, remove-device
      --rule stringArray      Rule in format seq[seq-num],action[permit/deny],prefix[IPv4 prefix],ge[prefix-len],le[prefix-len]. Example: seq[5],action[permit],prefix[10.0.0.0/8],ge[10],le[24]
      --ip string        Comma separated range of device IP addresses. Example: 1.1.1.1-3,1.1.1.2,2.2.2.2

Following is an example of IPv4 prefix list update:

Add device: This example configures prefix list on the devices.

efa policy prefix-list update –-name prefix_v4 –-type ipv4 –-operation add-device --ip 10.20.246.10-11

Delete device: This example removes prefix list from the devices.

efa policy prefix-list update –-name prefix_v4 –-type ipv4 –-operation remove-device --ip 10.20.246.10-11

Add rule: This example adds rule to the already created prefix list.

efa policy prefix-list update –-name prefix_v4 –-type ipv4 –-operation add-rule –-rule seq[5],action[permit],prefix[10.0.0.0/8],ge[16]

Delete rule: This example removes rule from the existing prefix list.

efa policy prefix-list update –-name prefix_v4 –-type ipv4 –-operation remove-rule –-rule seq[5],action[permit],prefix[10.0.0.0/8],ge[16]

efa policy prefix-list list ?
Flags:
       --type string      Type of prefix-list. Valid types are ipv4
       --ip string        Comma separated range of device IP addresses. Example: 1.1.1.1-3,1.1.1.2,2.2.2.2

Following is an example of IPv4 prefix list show:

IPv4 prefix list show

efa policy prefix-list list –-type ipv4 –-ip 10.20.246.10-11

Name: prefix_v4
+------+---------+--------+------------+----+----+--------------+-------------+
| Type | Seq num | Action |   Prefix   | Ge | Le | DeviceIP     | AppState    |
+------+---------+--------+------------+----+----+--------------+-------------+
| ipv4 |    5    | permit | 10.0.0.0/8 | 16 |    | 10.20.246.10 | cfg-in-sync |
+------+---------+--------+------------+----+----+---------------+------------+
| ipv4 |    5    | permit | 10.0.0.0/8 | 16 |    | 10.20.246.11 | cfg-in-sync |
+------+---------+--------+------------+----+----+--------------+-------------+

This step deletes the prefix list on all devices and EFA.

efa policy prefix-list delete ?
Flags:
      --type string   Type of prefix-list. Valid types are ipv4
      --name string      Name of Prefix list

Following example deletes an IPv4 prefix list with name prefix_v4:

efa policy prefix-list delete –-type ipv4 –-name prefix_v4
