First of all: autoinstall works only on the first serial interface of the router, don’t forget it. This is the topology for the small lab: R1 is a TFTP server, it stores R3 configuration in flash. R3 has no configuration. R2 interface is configured as follow: `` interface Serial1/0 ip address 10.0.23.2 255.255.255.0 ip helper-address 220.127.116.11 encapsulation frame-relay ip ospf network broadcast ip ospf 1 area 0 serial restart-delay 0 frame-relay map ip 10.
Autoinstall is a quite interesting topic, it deserves some labbing. Start from the DOC-CD as usual, we focus on the LAN implementation first. You can find HERE the flowchart of the autoinstall process. This guide is quite clear too: AutoInstall Using DHCP for LAN Interfaces This is the topology we’ll use: R1 and R2 will start without configuration. R3 is the DHCP server that provides TFTP informations to R1 and R2.
