Description
Specify Dynamic Host Configuration Protocol (DHCP) relay parameters for a generated configuration for an Ethernet VPN (EVPN) fabric with Virtual Extensible LAN (VXLAN) encapsulation.
You use the statements in the [edit services evpn] hierarchy level to
simplify configuring an EVPN fabric with Ethernet segment identifier (ESI) link
aggregation groups (LAGs) in the topology. The feature you enable with statements in
this hierarchy is an easy EVPN LAG configuration feature, also called EZ-LAG.
You only need to configure a few statements to provide the parameters required for an
EVPN core fabric with multihomed or single-homed customer edge (CE) devices (or end
server devices). When you commit the [edit services evpn] configuration
statements, the device uses a commit script to generate the corresponding standard EVPN
fabric configuration statements.
The statements at the [edit services evpn evpn-vxlan dhcp-relay]
hierarchy level provide the DHCP relay parameters the commit script needs to generate a
default configuration for a DHCP relay group in an EVPN-VXLAN fabric.
Options
| name |
The group name to identify a DHCP server and relay group. The commit script generates configuration statements to create the DHCP relay group. |
| dhcp-server-address dhcp-server-address |
(Required) The IP address of the DHCP server. The commit script uses this address in the generated configuration to enable the DHCP relay server group. |
| relay-source DHCP-relay-source-interface |
The DHCP relay source loopback interface IP address. The commit script
generates DHCP |
| vrf-instance vrf-instance-id |
(Required) The virtual routing and forwarding (VRF) instance identifier for which you want to configure DHCP relay. You specify VRF instance IDs by number in this easy EVPN LAG configuration feature. The commit script appends the VRF instance ID to a default VRF instance name to generate the configuration statements for different tenant VRF instances.
