MPLS/VPN 实验： ISIS/EIGRP

此实验在前OSPF/STATIC的配置基础上，将配置改变，就可以作为此实验了。

需要改变的配置是CE - PE之间的协议,以及PE-P-PE之间的协议.

删除相关的静态配置以及OSPF协议.

在CE上配置EIGRP协议:

router eigrp 1
 network 1.1.1.1 0.0.0.0
 network 192.168.1.0 0.0.0.3
 no auto-summary

建立起EIGRP邻居：

CE1#sh ip eigrp neighbors
IP-EIGRP neighbors for process 1
H   Address                 Interface       Hold Uptime   SRTT   RTO  Q  Seq
                                            (sec)         (ms)       Cnt Num
0   192.168.1.2             Fa0/0             12 00:34:49   86  1161  0  6

在PE路由器上的配置：

EIGRP：

router eigrp 1
 network 192.168.1.0 0.0.0.3
 no auto-summary
 !
 address-family ipv4 vrf vpn
  redistribute bgp 100 metric 1000000 1 255 1 1500
  network 192.168.1.0 0.0.0.3
  auto-summary
  autonomous-system 1
 exit-address-family

在PE上输入这些配置之后,EIGRP邻居才会建立起来.

配置ISIS协议:

router isis
 net 49.2222.2222.2222.00
 is-type level-2-only

ISIS 协议配置的不多，就是启动此协议，然后在相应的接口上输入命令：ip router isis

BGP配置如:

!
router bgp 100
 no bgp default ipv4-unicast
 bgp log-neighbor-changes
 neighbor 4.4.4.4 remote-as 100
 neighbor 4.4.4.4 update-source Loopback0
 !
 address-family ipv4
  neighbor 4.4.4.4 activate
  no auto-summary
  no synchronization
 exit-address-family
 !
 address-family vpnv4
  neighbor 4.4.4.4 activate
  neighbor 4.4.4.4 send-community extended
 exit-address-family
 !
 address-family ipv4 vrf vpn
  redistribute eigrp 1 metric 10
  no synchronization
  network 192.168.1.0 mask 255.255.255.252
 exit-address-family
!

配置和前实验的相关不多，只是重分发的问题而已。
