17.2.3.2. BGP Networks
Figure 17.9. BGP Networks Menu
Neighbors are other BGP routers with which to exchange routing information. One or more neighbors
must be specified in order for BGP to operate. To add a neighbor to the BGP network, click on Add
a new neighbor to configure its BGP attributes.
Networks may be specified in order to add BGP routers connected to the specified subnets. Note
that a network specification need not be a given valid entry in the routing table. Since BGP is a border
gateway protocol, one would more typically enter a more general network specification here. For
example, if a routed network inside the AS comprised many different Class C subnets (/24) of the
192.168.0.0/16 range, it would be more efficient to advertise the one Class B network specification,
192.168.0.0/16, to one's BGP neighbors.
Note
If BGP Neighbors are specified but no Networks are specified, then the router will receive BGP
routing information from its neighbors but will not advertise any routes to them.
