IP Configuration
In order to function properly for IP traffic, the node must be informed of the local IP address and netmask setting. This is because the protocol includes an "inquire" packet which we must be prepared to answer. There are two ways to accomplish this, manually and automatically. Whenever such an inquire packet is received, the node sends a NGM_CISCO_GET_IPADDR control message to the peer node connected to the inet hook (if any). If the peer responds, then that response is used. This is the automatic method.
If the peer does not respond, the node falls back on its cached value for the IP address and netmask. This cached value can be set at any time with a NGM_CISCO_SET_IPADDR message, and this is the manual method.
If the inet hook is connected to the inet hook of an ng_iface(4) node, as is usually the case, then configuration is automatic as the ng_iface(4) understands the NGM_CISCO_GET_IPADDR message.
HOOKS
This node type supports the following hooks:
