Command mode::
Supervisor mode
Explanation:
You
can use command “show ip bgp
summary” to see some global configuraion about BGP protocol.such as global
distance configuraion, IGP
synchronization configuraion,ID
number of AS confederation,AS confederation member, local AS number, local router-id,
information of all nerghbors
Example:
The following
example display some information provided by “show ip bgp summary” :
router bgp 4
BGP local AS is 4
Router ID is 192.168.20.72
IGP synchronization is enabled
Distance: external 20 internal 200

192.168.20.12 4 5 0 0 0 0
0 never Connect
Relevant command:
use “synchronization”to enable the synchronization between BGP and
IGP.
use “no synchronization”to disable it.
synchronization
no synchronization
Parameter:
none
Default::
Synchronization is enabled
Command mode::
BGP CONFIGURATION MODE
Explanation:
Normally, you do not expect to redistribute all
routes to your IGP. A common design is to redistribute one or two routes, and
make them the external routes in IGRP, or force the BGP session to generate an
AS default route. When BGP redistribute routes to IGP, only the routes acquired
through EBGP will be redistributed. Under most situations, you do not want to
allocate your IGP to BGP, just use configuration command “network “ to list the
network in AS, then your network will be broadcasted. The networks listed in
this form are called local network, and enables BGP to have attribute “Origin”
of IGP. They must appear in the main IP routing table, and are effective; for
example, they are direct-connected routes, static routes or routes known
through IGP. BGP routing process periodically scans the main IP routing table
to check the existence of a local network, and accordingly updates BGP routing
table if you really want BGP to execute redistribution, you must be very
careful, because these may be the routes in IGP that are injected by other
routers through BGP, this may bring force a kind of situation that BGP
potentially injects the information into IGP, and then send back the
information to BGP. Vice versa. In Default,IGP function is enabled.
Example:
router bgp 120
no synchronization
Relevant command:
router bgp
set Route-map when
BGP add route to route-map to modify some performance .Use no table-mapto delete the
configuration.
table-map <name>
no table-map <name>
Parameter:
<name> Route-map
name
Default::
none
Command mode::
BGP CONFIGURATION
MODE
Explanation:
Setting table-map can filter route or modify
performance when BGP add route to route list.
Example::
none
Relevant command:
none
modify Default timers
of BGP neighbor,use no timers to resume the default value.
timers bgp <keepalive>
<holdtime>
no timers bgp <keepalive>
<holdtime>
Parameter:
<keepalive> Keepalive
interval of BGP neighbor
<holdtime> hodetime
interval of BGP neighbor
Default:
Keepalive: 60
seconds
Holdtime: 180
seconds

Example::
The following configuration will set the default
