When would you use DHCP relay?

A DHCP relay agent is a host or router that forwards DHCP packets between clients and servers. Network administrators can use the DHCP Relay service of the SD-WAN appliances to relay requests and replies between local DHCP Clients and a remote DHCP Server.

What is the main purpose of a DHCP relay agent?

The DHCP relay agent operates as the interface between DHCP clients and the server. The DHCP Relay Agent relays DHCP messages between DHCP clients and DHCP servers on different IP networks.

Is DHCP required in a network?

The host in any network can be assigned the IP address manually or dynamically. No two hosts can have the same IP address and assigning them IP address manually can lead to errors and confusion. So, to resolve this problem DHCP is needed. The DHCP is needed to simplify the assignment of IP addresses on a network.

What is the purpose of a DHCP relay agent in an NSX edge configuration?

The DHCP relay capability provided by NSX in VMware Cloud Director environment allows to leverage existing DHCP infrastructure from within VMware Cloud Director environment without any interruption to the IP address management in existing DHCP infrastructure.

Why do we need a DHCP relay agent?

This restriction requires all individual subnets have its own DHCP server for DHCP operation, which is practically not feasible in network operators’ networks or corporate computer networks (too many DHCP servers are required in the network!). To address this problem, the concept of a DHCP relay agent has long been adopted [1].

Do I need a DHCP Relay for PCPCC?

PCc is local to the DHCP server, so there is no need for a DHCP relay. The broadcast on VLAN 2 is forwarded to the DHCP server 10.1.1.100 via the DHCP relay function with the Gateway IP Address field filled in with the VLAN 2 IP of Switch A, 10.1.2.1.

What is dhdhcp relay agent notification for prefix delegation?

DHCP relay agent notification for prefix delegation allows the router working as a DHCPv6 relay agent to find prefix delegation options by reviewing the contents of a DHCP RELAY-REPLY packet that is being relayed by the relay agent to the client.

Why do we need a DHCP server?

The DHCP server requires the forwarding router’s IP address that is forwarding the DHCPDiscover, GIADDR. Without DHCP relay, there were need to be a DHCP server on every network/subnet/VLAN.
