Chapter 29 BGP Configuration
To inject the network information advertised by the BGP Speaker to its BGP Speaker by
means of the Network commands by manual, execute the following operations in the BGP
configuration mode:
Command
Router(config-router)# network
network-number mask network-mask
[route-map map-tag]
Use the no network network-number mask network-mask command to cancel the network
to be sent. If it is necessary to cancel the used route-map, configure it again by using the
Route-map Not Added option. If the configured network information is of standard class A,
class B or class C network address, the mask option of this command may not be used.
The BGP4+ supports the IPv6 routing, and this command can be used to configure the route
information of IPv6 in address-family ipv6.
Caution
Sometimes, we hope some route of IGP is optimal, and the route information of EBGP is not
used, so the configuration command network backdoor can be used to perform this
function. Execute the following operations in the BGP configuration mode:
Command
Router(config-router)# network
network-number mask network-mask
backdoor
Use the no network network-number mask network-mask backdoor command to cancel
the indicated backdoor network information.
Caution
29-4
1. The network command is used to inject the route of IGP into the route
table of BGP, and the advertised Networks may be direct-connected
route, static route and dynamic route.
2. For the external gateway protocol (EGP), the network command
indicates the network to be advertised, which is different from the
internal gateway protocol (IGP, such as OSPF and RIP). The latter
uses the network commands to determine where the routing update
will be sent to.
By default, the management distance of the network information learned
about from the BGP Speakers which establish the EBGP connection is 20.
Set the management distance of such network information by the network
backdoor as 200.
Hence, the identical network information learned from the IGP presents
higher priority. These networks learned from the IGP are considered as
the backdoor network, and will not be advertised.
