Ipv6 dhcp relay destination command

What is IPv6 DHCP relay destination?

Enables the IPv6 DHCP relay agent function and specifies the IPv6 address as a destination address to which the client messages are forwarded.

What is the command of DHCP relay?

A DHCP relay agent uses "ip helper-address" command to indicate the DHCP server's IP address. It will insert the IP address of the interface which has that command configured into the gateway IP address field of DHCP packet to let DHCP server know which IP address range should be used to allocate.

How do I find my DHCP relay?

Viewing the DHCP relay setting

Use the show config command (or show running for the running-config file) to display the current DHCP relay setting. NOTE: The DHCP relay and hop count increment settings appear in the show config command output only if the non-default values are configured.

What is the DHCP port number for IPv6?

DHCPv6 Client/Server/Relay Agent messages are exchanged over UDP ports 546 and 547. DHCPv6 Clients listen for DHCPv6 messages on UDP port 546, while DHCPv6 Servers and DHCPv6 Relay Agents listen for DHCPv6 messages on UDP port 547.

What is the command to configure IPv6 static route?

IPv6 Static Route Configuration

To enable it, you can enter the command 'ipv6 unicast-routing' in the global configuration mode. We can still enable IPv6 in every interface, but it only accepts IPv6 traffic on a specific interface and will not forward the traffic to another interface on which IPv6 is not enabled.

How do I manually assign IPv6 addresses?

In Settings go to Network & Internet and click the Properties button for the interface you wish to configure. Click the Edit button under IP settings, change the configuration type to Manual, enable IPv6, and populate your settings.

What is DHCP relay Option 82?

The DHCP relay agent information option (option 82) enables you to include additional useful information in the client-originated DHCP packets that the DHCP relay forwards to a DHCP server. You can configure the option 82 support globally or for a named group of interfaces.

What is DHCP VLAN relay?

The DHCP Relay feature enables relaying DHCP requests from stations on a VLAN to an external DHCP sever. A DHCP Relay must be activated globally and per VLAN. In Layer 2 mode, DHCP Relay can run on a VLAN with an IP interface defined on it.

What is DHCP relay IP helper address?

IP helper address: It's the address of DHCP server located in another LAN from which hosts, DHCP request will be answered. DHCP relay is used to forward DHCP broadcast requests on LAN as a unicast packet to a central server, while ip helper-address is the command used to enable DHCP relay in routers.

What is DHCP l2 relay?

DHCP relay agents eliminate the need to have a DHCP server on each physical network. Relay agents populate the giaddr field and also append the Relay Agent Information option to the DHCP messages. DHCP servers use this option for IP addresses and other parameter assignment policies.

Should I enable DHCP relay?

A DHCP relay simply forwards the DHCP requests to the DHCP server. It is needed when the DHCP server is not in the same subnet as the hosts needing a DHCP address.

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 DHCP relay and helper address?

DHCP relay is used to forward DHCP broadcast requests on LAN as a unicast packet to a central server, while ip helper-address is the command used to enable DHCP relay in routers.

Should I enable or disable DNS relay?

The device with DNS relay enabled directly forwards the DNS query packets to the external DNS server, and does not search the local cache. If the DNS client needs to obtain resource records on the DNS server in real time, enable the DNS relay function on the device.

What is DHCP relay Option 82?

What is the difference between DHCP disable and relay?

DHCP relay agent relays DHCP messages between DHCP client and DHCP server located in different subnets. Disabled—disables the DHCP relay service in the switch.

What is DHCP VLAN relay?

What port is used by DHCP relay?

The DHCP relay uses port 67 as both the source and destination ports to communicate with the DHCP server.

What is the difference between DHCP proxy and relay?

The important difference between a DHCP proxy agent and a DHCP relay agent is that the former replaces a DHCP server IP with the IP address of the concerned DHCP proxy agent in the DHCP Server Identifier (Option 54) field included in the DHCP Offer/Ack message.
