esi (BGP EVPN Multi-homing)

Ethernet Segment Identifier (ESI) is a 10-octet identifier value that denotes an Ethernet Segment. It is used to discover and group the various interfaces of a multi-homed client. This command is used to manually assign Ethernet Segment Identifier (ESI) value to the segment. The same local port-channel id should be used by the multi-homed leaf peers on links connected to the same host.

Syntax

esi es-id
[no] esi es-id

Parameters

es-id
The 10 digit ESI value. Manually assigned ESI values must be in Hexadecimal and should always start with 0x00.

Modes

Ethernet Segment mode within Ethernet and Port-channel interface modes.

Usage Guidelines

Ethernet Segment Identifier is a 10-octet identifier value that denotes an Ethernet Segment. It is used to discover and group the various interfaces of a multi-homed client.

The [no] format of the command removes the Ethernet Segment Identifier value mapped to ethernet segment of the selected interface.

Examples

The following example shows the configuration of a leaf node with connections to two different multi-homed hosts.

SLX(config)# interface Ethernet 0/1
SLX(conf-if-eth-0/1)#ethernet-segment
SLX(conf-if-eth-0/1-es)# esi 00:11:22:33:44:55:66:77:88:99
SLX(config)# interface Port-channel 1
SLX(config-Port-channel-1)# ethernet-segment
SLX(config-Port-channel-1-es)# esi 00:11:11:22:22:33:33:44:44:55
