* EIGRP로 재분배시 metric 값을 반드시 지정해 줘야 한다.

[참고] http://cafe.naver.com/neteg/83909

* 공통 부분 생략하고 eigrp와 bgp 부분만 기술함

R1#

router eigrp 1
 no auto-summary
 address-family ipv4 vrf AA
  redistribute bgp 1 metric 1 1 1 1 1500 <-- eigrp로 재분배시 반드시 매트릭 값이 있어야 됨.
  network 1.1.15.1 0.0.0.0
  no auto-summary
  autonomous-system 1  <--- 만약, ISP 내부에 IGP로서 EIGRP 1을 사용할수도 있으므로 구별 필요
 exit-address-family

router bgp 1
 no synchronization
 bgp router-id 1.1.1.1
 bgp log-neighbor-changes
 neighbor 1.1.4.4 remote-as 1
 neighbor 1.1.4.4 update-source Loopback0
 no auto-summary

 address-family vpnv4
  neighbor 1.1.4.4 activate
  neighbor 1.1.4.4 send-community both
 exit-address-family

 address-family ipv4 vrf AA
  redistribute eigrp 1
  no synchronization
 exit-address-family

R4#도 위와 비슷함

R5, R6는 평상시처럼 eigrp 설정함

R4#도 비슷함...

CE쪽에서도 ripv2 설정

[종합 확인] AA는 eigrp, BB는 RIPv2
