When a DHCP server is enabled and conﬁgured, it assigns and manages IP addresses from

a speciﬁed address pool to DHCP clients. The options supported by this server are sufﬁcient

for Windows 95 clients. If more IP addresses or options are required, a commercial DHCP

server (for example, Windows NT) should be used.

DHCP Relay Agent

Cisco 700 series routers can function as a DHCP relay agent. (The router can also act as a

DHCP server, but not both at the same time.) When conﬁgured, Cisco 700 series routers

relay DHCP requests and responses between DHCP clients and a speciﬁed DHCP server.

Use the set dhcp relay command, where the IP address is the address of the server to which

DHCP requests will be forwarded.

Cisco 700 series routers support port address translation (PAT) allowing a designated

private IP network to communicate with the outside world. When conﬁgured, Cisco 700

series routers translate source addresses from an IP private network to a single, global,

unique IP address before forwarding the packets to the outside world.

The router can be assigned an IP address from the remote device using Internet Protocol

Control Protocol (IPCP) address negotiation. The implementation is based on RFC1332. It

supports IPCP options 1 and 3. (It does not support option 2, TCP/IP Header Compression.)

IP unnumbered is also supported. IPCP address negotiation is on by default in any proﬁle

conﬁgured for IP routing. This feature does not support assigning addresses to remote

devices.

IP RIP Update Linkup

The IP Routing Information Protocol (RIP) Update Linkup option for IP RIP enables better

interoperability between the router and Cisco IOS software. If the IP RIP update is set to

link up for a WAN proﬁle, the IP RIP data is sent as soon as a connection is established and
