实验9.11.4d BGP对等体组
一、实验拓扑图:



二、具体实验:

实验需求：
ITAA是国际大型互联网技术培训中心，与之相连的有很多对等体，而这些对等体都是同等地位的，也就是说，对于这些对等体的邻居配置是相同的。所以为了简化配置过程，且便于管理，ITAA采用对等体组的配置方案。
基本配置：
R1:
SUB_A#sh run
Building configuration...

Current configuration : 1336 bytes
!
version 12.3
hostname SUB_A

interface Loopback0
ip address 1.1.1.1 255.255.255.0
!
interface Serial1/0
ip address 10.0.0.1 255.255.255.0
serial restart-delay 0
!
router bgp 100
no synchronization
bgp log-neighbor-changes
network 1.1.1.0 mask 255.255.255.0
neighbor 10.0.0.2 remote-as 200
no auto-summary
!
end
R2:
ITAA#sh run
Building configuration...

Current configuration : 1590 bytes
!
version 12.3
hostname ITAA
interface Loopback0
ip address 2.2.2.2 255.255.255.0
!
interface Serial1/0
ip address 20.0.0.2 255.255.255.0
serial restart-delay 0
!
interface Serial1/1
ip address 10.0.0.2 255.255.255.0
serial restart-delay 0
!
end
R3:
SUB_B#sh run
Building configuration...

Current configuration : 1295 bytes
!
version 12.3
hostname SUB_B
interface Serial1/1
ip address 20.0.0.3 255.255.255.0
serial restart-delay 0
!
router bgp 300
no synchronization
bgp log-neighbor-changes
network 3.3.3.0 mask 255.255.255.0
neighbor 20.0.0.2 remote-as 200
no auto-summary
!
end
连通性测试：
ITAA#ping 10.0.0.1

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.0.0.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 92/189/316 ms
ITAA#ping 20.0.0.3

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 20.0.0.3, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 24/105/200 ms
配置对等体组：
ITAA(config)#router bgp 200
ITAA(config-router)#bgp log-neighbor-changes
ITAA(config-router)#network 2.2.2.0 mask 255.255.255.0
ITAA(config-router)# neighbor GROUP peer-group
ITAA(config-router)# neighbor GROUP send-community
ITAA(config-router)# neighbor GROUP route-map LIMIT out
ITAA(config-router)# neighbor 10.0.0.1 remote-as 100
ITAA(config-router)# neighbor 10.0.0.1 peer-group GROUP
ITAA(config-router)# neighbor 20.0.0.3 remote-as 300
ITAA(config-router)# neighbor 20.0.0.3 peer-group GROUP
ITAA(config)#route-map LIMIT permit 10
ITAA(config)# set community 40
ITAA(config)#exit
对等体配置验证（客户端）：
SUB_A#sh ip bgp
BGP table version is 5, local router ID is 1.1.1.1
Status codes: s suppressed, d damped, h history, * valid, > best, i - internal,
r RIB-failure, S Stale
Origin codes: i - IGP, e - EGP, ? - incomplete

Network Next Hop Metric LocPrf Weight Path
*> 1.1.1.0/24 0.0.0.0 0 32768 i
*> 2.2.2.0/24 10.0.0.2 0 0 200 i
SUB_A#sh ip bgp 2.2.2.0
BGP routing table entry for 2.2.2.0/24, version 5
Paths: (1 available, best #1, table Default-IP-Routing-Table)
Not advertised to any peer
200
10.0.0.2 from 10.0.0.2 (2.2.2.2)
Origin IGP, metric 0, localpref 100, valid, external, best
Community: 40
重点突出的部分就是验证的结果，在ITAA的其他对等体上已经可以收到2.2.2.0的路由条目，并且团体属性值也为40.

对等体配置验证（ITAA发布端）：
ITAA#sh ip bgp nei
BGP neighbor is 10.0.0.1, remote AS 100, external link
Member of peer-group GROUP for session parameters
BGP version 4, remote router ID 1.1.1.1
……….
BGP neighbor is 20.0.0.3, remote AS 300, external link
Member of peer-group GROUP for session parameters
BGP version 4, remote router ID 20.0.0.3
……….
