Configuring Dhcp And Bootp Relay; Dhcp; Bootp - Avaya G350 Administration

•
Use the
key for the tunnel. Tunnel ID keys are used as a security device. The key is set for the same value
at each of the tunnel endpoints. Packets without the configured key must be discarded. Use the
form of this command to disable key checking.
•
Use the
value to packets traveling through the tunnel. The DSCP value is placed in the packet's Carrier IP
header. You can assign a DSCP value between 0 and 63. If you do not assign a DSCP value, the
DSCP value is copied from the packet's original IP header.
NOTE:
The Carrier IP header identifies the source and destination IP address of the tunnel.
•
Use the
packets traveling through the tunnel. The TTL value is placed in the packet's Carrier IP header.
You can assign a TTL value between 1 and 255. The default tunnel TTL value is 255.
•
Use the
particular tunnel or all GRE tunnels.
NOTE:
If the tunnel interface is down, the
value of 0.

Configuring DHCP and BOOTP relay

When you configure Dynamic Host Configuration Protocol (DHCP) and BOOTstrap Protocol (BOOTP)
relay, you can control how the router relays DHCP and BOOTP packets. The router can relay DHCP and
BOOTP client broadcasts to a server on a different segment of the network. The router also relays replies
from the server back to the client.

DHCP

DHCP assigns dynamic IP addresses to devices on a network. With dynamic addressing, a device can
have a different IP address whenever the device connects to the network. In some systems, the device's IP
address can even change while it is still connected. DHCP also supports a mix of static and dynamic IP
addresses.
Dynamic addressing simplifies network administration because the software keeps track of IP addresses
rather than requiring an administrator to manage the task. This means you can add a new computer to a
network without the hassle of manually assigning a unique IP address. Many ISPs use dynamic IP
addressing for dial-up users. However, dynamic addressing may not be desirable for a network server.

BOOTP

BOOTP is an Internet protocol that allows a diskless workstation to discover the following:
•
Its own IP address
•
The IP address of a BOOTP server on the network
•
A file to be loaded into memory to boot the workstation
