這Lab學習目標為
In this lab, you will configure IBGP routers to use a route reflector and a simple route filter.
我的設定是
1. Configure RIPv2
Use RIPv2 as the IGP. Do not configure the 199.9.9.0 network under the RIP process.
SanJose1:
hostname SanJose1
!
no ip domain lookup
!
interface Serial0/0
ip address 192.168.1.5 255.255.255.252
no shutdown
!
router rip
version 2
network 192.168.1.0
no auto-summary
!
line con 0
exec-timeout 0 0
logging synchronous
!
end
SanJose2:
hostname SanJose2
!
no ip domain lookup
!
interface Loopback0
ip address 200.100.50.1 255.255.255.0
!
interface Serial0/0
ip address 192.168.1.6 255.255.255.252
no shutdown
!
interface Serial0/1
ip address 172.24.1.17 255.255.255.0
no shutdown
!
router rip
version 2
network 172.24.0.0
network 192.168.1.0
network 200.100.50.0
no auto-summary
!
line con 0
exec-timeout 0 0
logging synchronous
!
end
SanJose3:
hostname SanJose3
!
no ip domain lookup
!
interface Serial0/1
ip address 172.24.1.18 255.255.255.0
no shutdown
!
router rip
version 2
network 172.24.0.0
no auto-summary
!
line con 0
exec-timeout 0 0
logging synchronous
!
end
2. IBGP Peers and Route Reflectors
Configure the IBGP peers for BGP.
SanJose1:
router bgp 100
neighbor 192.168.1.6 remote-as 100
SanJose2:
router bgp 100
network 172.24.1.0 mask 255.255.255.0
network 192.168.1.0 mask 255.255.255.252
network 200.100.50.0
neighbor 172.24.1.18 remote-as 100
neighbor 192.168.1.5 remote-as 100
SanJose3:
router bgp 100
neighbor 172.24.1.17 remote-as 100
3. Inject an External Route into BGP
configure SanJose3 to inject external routing information into BGP
SanJose3:
interface Loopback0
ip address 199.9.9.1 255.255.255.0
!
router bgp 100
network 199.9.9.0
SanJose2:
router bgp 100
neighbor 172.24.1.18 route-reflector-client
neighbor 192.168.1.5 route-reflector-client
4. Inject a Summary Address into BGP
Configure SanJose3 to inject a summary address into BGP.Configure a route filter to prevent SanJose2 from sending the 199.9.9.0/24 route to its other clients, in this case to SanJose1.
SanJose3:
router bgp 100
aggregate-address 199.0.0.0 255.0.0.0
!
show ip bgp 199.0.0.0
!
Configure a route filter to prevent SanJose2 from sending the 199.9.9.0/24 route to its other clients, in this case to SanJose1.
SanJose2:
!
ip prefix-list Supernetonly seq 5 permit 199.0.0.0/8
ip prefix-list Supernetonly seq 10 permit 172.24.0.0/24
ip prefix-list Supernetonly seq 15 permit 200.100.50.0/24
!
router bgp 100
neighbor 192.168.1.5 prefix-list Supernetonly out
SanJose1:
clear ip bgp *
!
show ip route
