[ Network / MPLS ] MPLS - static routing 으로 구성하기

구성

 스텝 1 . EIGRP AS 100 구성

<R1>
router eigrp 100
 network 1.1.1.1 0.0.0.0
 network 1.1.12.1 0.0.0.0

<R2>
router eigrp 100
 network 1.1.2.2 0.0.0.0
 network 1.1.12.2 0.0.0.0
 network 1.1.23.1 0.0.0.0

<R3>
router eigrp 100
 network 1.1.3.3 0.0.0.0
 network 1.1.23.2 0.0.0.0
 network 1.1.34.1 0.0.0.0

<R4>
router eigrp 100
 network 1.1.4.4 0.0.0.0
 network 1.1.34.2 0.0.0.0

 스텝 2.  BGP AS 100 구성

반응형

<R1>
router bgp 100
 neighbor 1.1.4.4 remote-as 100
 neighbor 1.1.4.4 update-source loopback 0
<R4>
router bgp 100
 neighbor 1.1.1.1 remote-as 100
 neighbor 1.1.1.1 update-source Loopback0

 스텝3. MPLS 구성

<R1,R2,R3,R4>
ip cef
mpls label protocol ldp
mpls ldp router-id loopback 0
<R1>
int g0/2
 mpls ip
<R2>
int g0/1
  mpls ip
int g0/0
  mpls ip
<R3>
int g0/0
  mpls ip 
int g0/1
  mpls ip
<R4>
int g0/1
  mpls ip

 스텝 4 . VRF 구성

[ STATIC ROUTE설정]
R5
	ip route 192.168.11.0 255.255.255.0 2.2.12.2
R6
	ip route 192.168.10.0 255.255.255.0 22.2.12.1
R7
	ip route 192.168.21.0 255.255.255.0 3.3.12.1
R8
	ip route 192.168.20.0 255.255.255.0 33.2.12.1

[VRF 설정]
<R1>
Router(config)#ip vrf A
Router(config-vrf)#rd 1:1
Router(config-vrf)#route-target 1:1
Router(config-vrf)#
Router(config-vrf)#int g0/1
Router(config-if)#ip vrf forwarding A
% Interface GigabitEthernet0/1 IPv4 disabled and address(es) removed due to enabling VRF A
Router(config-if)#ip add 2.2.12.2 255.255.255.0
Router(config)#ip vrf C
Router(config-vrf)#rd 3:3
Router(config-vrf)#route-target 3:3
Router(config-vrf)#exit
Router(config)#int g0/0
Router(config-if)#ip vrf forwarding C
Router(config-if)#ip add 3.3.12.1 255.255.255.0
<R4>
R4(config)#ip vrf B
R4(config-vrf)#rd 2:2
R4(config-vrf)#route-tar
R4(config-vrf)#route-target 2:2
R4(config-vrf)#
R4(config-vrf)#int g0/0
R4(config-if)#ip vrf forwarding B
% Interface GigabitEthernet0/0 IPv4 disabled and address(es) removed due to enabling VRF B
R4(config-if)#ip add 22.2.12.1 255.255.255.0
R4(config-if)#exit
R4(config)#ip vrf D
R4(config-vrf)#rd 4:4
R4(config-vrf)#route-target 4:4
R4(config-vrf)#int g0/2
R4(config-if)#ip vrf forwarding D
% Interface GigabitEthernet0/2 IPv4 disabled and address(es) removed due to enabling VRF D
R4(config-if)#ip add 33.2.12.1 255.255.255.0

 스텝5 .BGP를 이용 해 VRF 간  재분배 구성

<R1>
ip route vrf A 192.168.10.0 255.255.255.0 2.2.12.1
ip route vrf C 192.168.20.0 255.255.255.0 3.3.12.2
!
router bgp 100
address-family vpnv4
  neighbor 1.1.4.4 activate
  neighbor 1.1.4.4 send-community both
address-familu ipv4 vrf A
  redistribute static
address-family ipv4 vrf C
  redistribute static

ip vrf A
 route-target import 2:2
ip vrf C
 route-target import 4:4
 
<R4>
ip route vrf B 192.168.11.0 255.255.255.0 22.2.12.2
ip route vrf D 192.168.21.0 255.255.255.0 33.3.12.2
!
router bgp 100
address-family vpnv4
  neighbor 1.1.1.1 activate
  neighbor 1.1.1.1 send-community both
address-family ipv4 vrf B
  redistribute static
address-family ipv4 vrf D
  redistribute static

ip vrf B
 route-target import 1:1
ip vrf D
 route-target import 3:3

 BGP 를 이용해 공인 네트워크 구성

<R9>
router bgp 200
neighbor 5.5.12.2 remote-as 100
network 192.168.30.0 mask 255.255.255.0
<R1>
router bgp 100
neighbor 5.5.12.1 remote-as 200
neighbor 1.1.4.4 next-hop-self
<R4>
router bgp 100
neighbor 6.6.12.2 remote-as 200
neighbor 1.1.1.1 next-hop-self
<R10>
router bgp 200
neighbor 6.6.12.1 remote-as 100
network 192.168.31.0 255.255.255.0

 결과

<bgp 확인>

R1과 R2에서  #show bgp all

<컴퓨터 간 통신>

LS-A ------- LS-C => 통신 O 이 이외의 대역대는 통신되지 않는다.

LS-B --------LS_D =>통신 O-> 이 이외의 대역대는 통신되지않는다.

공인 네트워크는 공인 네트워크 끼리 통신된다. 

 

 

[다음으로 OSPF 로 구성해보도록 하겠습니다.]
