Configuring General IP Parameters

Use the IP Routing General window to set the internal IP address, router ID, routing table size and reassembly buffer size.

Procedure:

Step Action
1 Enter the internal IP address.

Note: It is recommended that you set the internal IP address, because ping, traceroute, and tftp packets sent by the router use this address.

2 Enter the router ID.  The router ID must match one of the configured IP interface addresses of the router.
3 Enter the routing table size. 

Note: Setting the size too small causes dynamic routing information to be discarded.  Setting the size too large wastes router memory resources.

4 Enter the reassembly buffer size. 
5 Click Apply.

 

Field Descriptions

Internal IP Address This address (or the Router ID if this address is not specified) is used as the source address in pings, traceroute and tftp packets generated by the router.  If neither the internal address or router ID is specified, then the first configured IP address is used as the source address for ping, traceroute and tftp packets.
Router ID This address must be one of the configured IP addresses.  If neither the internal address or router ID is specified, then the first configured IP address is used as the source address for ping, traceroute and tftp packets.  This address is also used as the OSPF router ID as long as it matches an OSPF interface address.
Routing Table Size Sets the size of the router's IP routing table.  The default size is 768 entries.  Changing this field takes effect only after a restart.
Reassembly Buffer Size Configures the size of the buffers that are used for the reassembly of fragmented terminating IP packets.  Changing this field takes effect only after a restart.
Configured Addresses Available for Router ID Lists all the available configured IP addresses and their associated Ifc numbers you can use.  The router ID must use one of these addresses.
