Important Considerations

For the CoreBuilder 3500 only, the system prompts you for an IP address and subnet mask. As a result, you can display only a subset of routes instead of all routes. To see all entries in the table, simply press Enter at these prompts.

The first line in the output (the status line) indicates whether IP routing is enabled:

For the CoreBuilder 9000 Layer 3 module, it also indicates whether Internet Control Message Protocol (ICMP) router discovery is enabled on the system.

For the CoreBuilder 3500, IP interface options (such as ICMP router discovery) appear under “ip interface detail” earlier in this chapter and are set on a per-interface basis.
