## CLI Syntax
### Ethernet Segment Identifier
Some route types requires to specify Ethernet Segment Identifier (ESI) for its
argument. The supported ESI types and their formats are the following.
| Type | Format | Description |
| ---- | -------------------------------------- | ------------------------------------------------------------------------------------------------------------- |
| 0 | single-homed | Reserved keyword for arbitrary ESI type to denote a single-homed site. |
| 0 | 0 | The same with "single-homed". |
| 0 | ARBITRARY \<Value> | Arbitrary ESI type with arbitrary value. Value should be colon separated hex values (similar to MAC address). |
| 1 | LACP \<MAC> \<Port Key> | Type for LACP configured segment. |
| 2 | MSTP \<MAC> \<Priority> | Type for L2 bridge protocol (e.g., Multiple Spanning Tree Protocol) configured segment. |
| 3 | MAC \<MAC> \<Discriminator> | Type for ESI based on MAC address. |
| 4 | ROUTERID \<Router ID> \<Discriminator> | Type for ESI based on Router ID. |
| 5 | AS \<AS> \<Discriminator> | Type for ESI based on AS number. |
