What is Relay Agent in BOOTP?
A BOOTP relay agent listens to UDP port 68, and forwards BOOTP request packets received on this port to the destinations specified on the command line. The relay agent can run on any machine that has knowledge of local routers, so it does not have to be an Internet gateway machine.
What is the purpose of relay agent?
The DHCP relay agent is any TCP/IP host which is used to forward requests and replies between the DHCP server and client when the server is present on a different network. Relay agents receive DHCP messages and then generate a new DHCP message to send out on another INTERFACE.
What is a DHCP relay agent and why is it needed?
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.
What is the difference between DHCP and BOOTP?
BOOTP, Bootstrap protocol, is used to configure host and get address of host along with bootstrap info. DHCP, Dynamic Host Configuration Protocol Server is an extended version of BOOTP and is used to configure hosts mechanically. BOOTP has no support for temporary IP Addressing.
What is the function of relay agent in BOOTP protocol to solve the problem of RARP?
A relay agent can be placed on networks where there are BOOTP clients but no BOOTP servers. The relay agent intercepts requests from clients and relays them to the server. The server then responds back to the agent, which forwards the response to the client.
What is difference between bootp and DHCP?
BOOTP, Bootstrap protocol, is used to configure host and get address of host along with bootstrap info. DHCP, Dynamic Host Configuration Protocol Server is an extended version of BOOTP and is used to configure hosts mechanically. BOOTP has no support for temporary IP Addressing. …
Can a juniper switch be both a DHCP/BOOTP relay agent?
Because DHCP and BOOTP messages are broadcast and are not directed to a specific server, switch, or router, Juniper switches cannot function as both a DHCP server and a DHCP/BOOTP relay agent at the same time.
What is a DHCP/BOOTP relay agent?
This means that if the switch receives a broadcast DHCP or BOOTP request from a locally attached host (client), it relays the message to a specified DHCP or BOOTP server. You should configure the switch to be a DHCP/BOOTP relay agent if you have locally attached hosts and a distant DHCP or BOOTP server.
How do I configure the QFX series as a DHCP/BOOTP relay agent?
You can configure the QFX Series to act as a Dynamic Host Configuration Protocol (DHCP) and Bootstrap Protocol (BOOTP) relay agent. This means that if a locally attached host can issue a DHCP or BOOTP request as a broadcast message and the switch relays the message to a specified DHCP or BOOTP server.
When is a switch a relay agent?
When a switch is a relay agent, if a locally attached host issues a DHCP or BOOTP request as a broadcast message, the switch relays the message to a specified DHCP or BOOTP server. You should configure a switch to be a DHCP and BOOTP relay agent if you have locally attached hosts and a remote DHCP or BOOTP server.
