Nortel Networks 14.2 Displaying the BootP Server IP Routes, Netstat -rn grep -i -n IPaddress

Troubleshooting Network Boot Problems

Note that /$HOME/.builder_dir/rel<rel>/an is the default location of the kernel file and all application and string files for the AN/ANH. The default location of the kernel file and all application and string files for the ARN is /$HOME/.builder_dir/rel<rel>/arn.

5.Ensure that the bootptab file contains a definition for the router that is failing to netboot.

6.Ensure that the configuration file name and path are correct in the bootptab file.

For example, the following bootptab entry indicates that the configuration file named AN_Bost.cfg is in the /rte3/cfg directory:

T129="/rte3/cfg/AN_Bost.cfg"

7.Read the bootptab file carefully for misspellings or other errors.

Compare it with the sample file shown in Chapter 2 (see Figure 2-1 on page 2-8).

Displaying the BootP Server IP Routes

To display the IP address of the next-hop router, enter the following command at the UNIX command line of the BootP server:

netstat -rn grep -i -n <IP_address>

IP_address is the IP address of the netbooting router’s network.

For example, enter netstat -rn grep -i-n 192.32.155 to display the IP address of the next hop to the network address 192.32.155.

If the BootP server is receiving RIP advertisements of the netbooting router’s network, a message such as the following appears:

121:192.32.155.0 192.32.13.53 UG 0 0 le0

The numbers in this message indicate the following:

•121 is the number of the entry in the workstation’s static routing table.

•192.32.155.0 is the IP address of the destination network.

•192.32.13.53 is the address of the next-hop router.

If the next-hop router is unavailable or incorrect, see “Setting Up Static Routes to Next-Hop Routers” in Chapter 2.
