Customizing NetBIOS over IP
117358-A Rev. A 8-3
By default, the NetBIOS Insertion of Record Route option in rebroadcast packets
is disabled. You can use Site Manager to enable the option.
If all IP entities support this option, enable it on the router.
Configuring a NetBIOS Cache
NetBIOS is a broadcast-intensive protocol. Much of the broadcast overhead is
related to maintaining unique names across the network and providing end users
with access to NetBIOS applications. The amount of overhead grows with the
number of NetBIOS resources (applications, servers, and clients) on the network.
To keep broadcast traffic to a minimum, each router that runs NetBIOS over IP
builds and maintains a cache of NetBIOS name/IP address pairs, using
information contained in the name query responses it receives and forwards.
In Figure 2-9 on page 2-23, for example:
1. Router A receives a name query response from the server. The router gleans
from the name query response the name and IP address of the server.
2. The router stores the name and IP address of the server in its cache.
3. The router forwards the name query response.
