Networks

 

The networks associated with the BGP route. Enter one or more network

 

 

 

addresses or network/host objects, or click Select to display an Object

 

 

 

Selectors, page F-593.

 

 

 

If the network you want is not listed, click the Create button in the selector

 

 

 

to display the Network/Host Dialog Box, page F-477. From here you can

 

 

 

define a network/host object.

 

 

 

Note To remove a network from the route, select it from the Network field,

 

 

 

then click Delete.

 

 

 

 

 

Neighbors

 

The internal neighbors (those located in the same AS as the router) and

 

 

 

external neighbors (located in different ASs) of the router. See Neighbors

 

 

 

Dialog Box, page K-222.

 

 

 

 

 

Auto-Summary

 

When selected, automatic summarization is enabled. When a subnet is

 

 

 

redistributed from an IGP (such as RIP, OSPF or EIGRP) into BGP, this BGP

 

 

 

version 3 feature injects only the network route into the BGP table.

 

 

 

Automatic summarization reduces the size and complexity of the routing

 

 

 

table that the router must maintain.

 

 

 

When deselected, automatic summarization is disabled. This is the default.

 

 

 

 

 

Synchronization

 

When selected, synchronization is enabled. Use this feature to ensure that all

 

 

 

routers in your network are consistent about the routes they advertise.

 

 

 

Synchronization forces BGP to wait until the IGP propagates routing

 

 

 

information across the AS.

 

 

 

When deselected, synchronization is disabled. You can disable

 

 

 

synchronization if this router does not pass traffic from a different AS to a

 

 

 

third AS, or if all the routers in the AS are running BGP. Disabling this

 

 

 

feature has the benefit of reducing the number of routes the IGP must carry,

 

 

 

which improves convergence times. This is the default.

 

 

 

 

 

Log-Neighbor

 

When selected, enables the logging of messages that are generated when a

 

 

 

BGP neighbors resets, connects to the network, or is disconnected. This is

 

 

 

the default.

 

 

 

When deselected, message logging is disabled.
