Dynamic Reconfiguration

With dynamic reconfiguration, any changes you make to a router take place automatically without the router being restarted.

Any protocol parameter changes (from the Protocols menu in NIASCFG) to TCP/IP, IPX, or AppleTalk parameters take place dynamically at reinitialization. Status changes and configuration changes in any routing protocol take place dynamically without affecting other routing protocols.

All bind configuration changes (from the Bindings menu in NIASCFG) cause an automatic unbind and rebind to the interface.

This topic contains the following sections:

• IPX
• TCP/IP
• AppleTalk

IPX

The following conditions are true for IPX:

• All global configuration changes will cause an automatic unload and reload of IPX.
• Port-specific parameter changes or WAN call profile changes might or might not bring the affected connection down, depending on the type of change being made. Only permanent connections will be brought up again.
• Any configuration changes to the static routes or services for a circuit will delete and refresh all static routes and services for that circuit without disconnecting the call.

TCP/IP

The following conditions are true for TCP/IP:

• All configuration changes, except to WAN Call Destinations , RIP Bind Options , and OSPF Bind Options , cause an automatic unbind and rebind of IP to the interface.
• Any configuration changes to RIP Bind Options and OSPF Bind Options will simply reconfigure the respective routing protocol without affecting other routing protocol bind parameters.
• Any configuration changes to WAN Call Destinations , except changes to Static Routing Table and RIP Bind Options , will bring the connection down. Only permanent, automatic connections will be brought up again.
• Any configuration changes to RIP Bind Options or Static Routing Table under WAN Call Destinations will reconfigure RIP or the static routes for the specified connection without affecting other parameters, and without disconnecting the call for the given connection.

AppleTalk

The following conditions are true for AppleTalk:

• All AppleTalk configuration parameter changes are dynamically reconfigured immediately, except changes to the WAN Protocol ID (PID). You must restart the router to use a new Protocol ID.
• Binding configuration changes, except those made to WAN call destinations, automatically unbind and rebind AppleTalk to the interface.
• Any configuration changes to the zone(s) list for an external interface will cause an automatic unbind. You must enter the REINITIALIZE SYSTEM command to rebind AppleTalk to the interface 10 minutes later.
• Any configuration changes to the zone(s) list of the internal network and the static routes will make AppleTalk not advertise the changed routes for 10 minutes.
• Any configuration changes to the WAN interface or WAN call destinations, except changes to the static routes, will bring the connection down. Only permanent, automatic connections are brought up again.
• Any configuration changes to static routes will reconfigure the static routes for the specified connection without affecting other parameters, and without disconnecting the call for the given connection.
• Any configuration changes to the AURP parameters will make AURP unload and reload internally, and all connected AURP peers will be disconnected and reconnected.
