AutoInstall notes...

I've been trying to nail down autoinstall just in case I get the dreaded
autoinstall over frame-relay scenario
on my Lab. Using info I found on the net I put some notes together on it.
Would some of you mind looking
through my notes and telling me if I'm missing anything or if anything is
wrong?

Thanks,
Bryan R.

Auto-Install:
Happens in steps:
1. DHCP to get IP. (optional)
2. Name-server lookup to get host name.
3. TFTP server to get config file.

There are 4 "Functions" involved with this:
1. DHCP -Gives AI Router an IP.
2. DNS Server -Gives AI Router it's Name.
3. TFTP Server -Gives AI Router it's config file.
4. Hub -Optional. If exists need helper maps pointing to tftp & DNS servers
AND
          "ip name-server" and domain-lookup configured. Possibly DHCP
configured.

CONFIGURATION:
R5 is AI Router. R1 is the TFTP server, R6 is the DNS server and R4 is a FR
hub.

R1: -TFTP Server

"tftp-server flash:r5-confg"
-Note that the file must be in the flash of the device.

R6: -DNS Server

ip host r5 155.1.0.5
ip dns server
ip domain-lookup

R4: -FR Hub & DHCP Server.

ip domain-lookup
ip name-server 155.1.146.6
interface Serial0/0
ip address 155.1.0.4 255.255.255.0
ip helper-address 155.1.146.1 <-IP's of tftp and dns servers.
ip helper-address 155.1.146.6
encapsulation frame-relay
frame-relay map ip 155.1.0.5 405 broadcast
no frame-relay inverse-arp <-No inverse-arp, so need frame
map on
                                             AI Router.

ip dhcp exclude-address 155.1.0.1 155.1.0.4
ip dhcp exclude-address 155.1.0.6 155.1.0.255
ip dhcp pool
network 155.1.0.0 /24

R5: -AutoInstall router

no frame-relay inverse-arp
