This blog was originally started to better help me understand the technologies in the CCIE R&S blueprint; after completing the R&S track I have decided to transition the blog into a technology blog.
CCIE #29033
This blog will continue to include questions, troubleshooting scenarios, and references to existing and new technologies but will grow to include a variety of different platforms and technologies. Currently I have created over 185 questions/answers in regards to the CCIE R&S track!! Note: answers are in the comment field or within "Read More" section.

When doing an auto-install over frame-relay what considerations need to be made?
1 comments:
AutoInstall over a Frame Relay requirements
1. Serial connection to the network and router powered on.
2. AutoInstall process brings up the interface and learns the DLCI.
3. A frame map is created.
4. The new router sends a BOOTP request to the remote end.
5. BOOTP server replies to the request with an IP address. The new router now has an IP address.
6. The new router broadcasts TFTP request looking for a configuration file. The remote router has an IP helper address to forward this request to a TFTP server.
7. Configuration file is sent by the TFTP server and the new router loads the conifguration.
8. This completes the AutoInstall and the new router is up and running.
Example: R10 - is the new router (R10 is connected to R20 over frame-relay. R20 has a TFTP server off its fastethernet 0/1 interface. TFTP server ip address is 10.0.0.100/24.
Create configuration file and save it as r10-config on the TFTP server
hostname r10
!
enable secret cisco
!
interface fastethernet0/1
ip address 10.0.1.10 255.255.255.0
no shutdown
!
interface Serial0/1
ip address 192.168.1.10 255.255.255.0
encapsulation frame-relay
no fair-queue
frame-relay map ip 192.168.1.20 102 broadcast
no shutdown
!
router rip
version 2
network 192.168.0.0
network 10.0.0.0
no auto-summary
!
line vty 0 4
password cisco
login
!
end
Create a network configuration file and save it on the
TFTP server as network-config
ip host r10 192.168.1.10
R20
__
hostname r20
!
enable secret cisco
!
interface Fastethernet0/1
ip address 10.0.0.1 255.255.255.0
!
interface Serial0
ip address 192.168.1.20 255.255.255.0
ip helper-address 10.0.0.100
encapsulation frame-relay
no fair-queue
frame-relay map ip 192.168.1.10 201 broadcast

router rip
version 2
network 192.168.0.0
network 10.0.0.0
no auto-summary

line vty 0 4
password cisco
