How to Configure Network Management Features on ASR 901
Configuring a TFTP Server
You need to set up a TFTP server to provide a bootstrap configuration to the ASR 901 routers when they
boot using option 150.
Creating a Bootstrap Configuration
Create or download a file with the initial bootstrap configuration on the TFTP server. An example of the
configuration file is shown below:
hostname test-router
!
cns trusted-server all-agents 30.30.1.20
cns event 30.30.1.20 11011 keepalive 60 3
cns config initial 30.30.1.20 80
cns config partial 30.30.1.20 80
cns id hostname
Step 4
ip dhcp excluded-address
ip-address subnet-mask
Example:
Router# ip dhcp excluded-address 30.30.1.20
30.30.1.255
Assigns IP addresses with an exception of 30.30.1.6, which
is the IP address of the DHCP server.
Step 5
ip dhcp pool
pool-name
Example:
Router# ip dhcp pabudhcp2
Specifies the DHCP pool name.
Step 6
network
ip-address subnet-mask
Example:
Router# network 160.100.100.0 255.255.255.252
Specifies the IP address and subnet mask of the network.
Step 7
default-router
ip-address
Example:
Router# default-router 30.30.1.6
Specifies the IP address of the default router.
Step 8
option 43 ascii
string
or
option 150 ip <
TFTP-server-ip-address
>
Example:
Router# option 43 ascii 3A1D;A3;B161.100.100.2
Specifies Option 43 and a string value that has the CNS
details, serial number of the hardware, and the code for CE
IP address or Option 150 and the IP address of the TFTP
server.
