欢迎您访问我爱IT技术网，今天小编为你分享的电脑教程是网络协议方面的经验知识教程：MPLS／VPN实验一：OSPF／STATIC，下面是详细的分享！
MPLS／VPN实验一：OSPF／STATIC
MPLS/VPN实验一：OSPF/STATIC
有关一些MPLS 其中的术语在这里就不作解释了，直接跳到实验部分。
在 pe-p-p 之间用到的IGP协议是OSPF,而在CE-PE之间用到的协议是静态.
网络拓扑图如下所示:
按此图作好基本配置如下所示：
ce1: int l0 1.1.1.1/32
f0/0 192.168.1.1 255.255.255.252
pe1: int 0 2.2.2.2/32
f0/0 192.168.1.2/30
f0/1 10.1.1.1/30
p: int l0 3.3.3.3/32
f0/1 10.1.1.2/30
f0/0 10.1.1.5/30
pe2: int l0 4.4.4.4/32
f0/0 10.1.1.6/30
f0/1 192.168.2.1/30
ce2: int l0 5.5.5.5/32
f0/1 192.168.2.2/30
在MPLS区域上启动MPLS 协议:
例：
int f0/1
mpls lap pro ldp
mpls ldp
在这之前是需要是启动CEF,其实也就是需要借助于FIB.
查看邻居关系是否建立起来了,show mpls ldp nei 或者是用命令:show mpls ldp dis det
PE1#sh mpls ldp neighbor
Peer LDP Ident: 3.3.3.3:0; Local LDP Ident 2.2.2.2:0
TCP connection: 3.3.3.3.60098 - 2.2.2.2.646
State: Oper; Msgs sent/rcvd: 45/43; Downstream
Up time: 00:30:01

PE1#sh mpls ldp discovery detail

进行测试：
PE1#traceroute 4.4.4.4
Type escape sequence to abort.
Tracing the route to 4.4.4.4

成功/
在CE上配置静态路由;
CE1#sh run | in ip route
ip route 0.0.0.0 0.0.0.0 192.168.1.2
CE1#
在这里配置的是默认路由；
在PE1上配置VRF：
ip vrf vpn
rd 100:1
route-target export 100:1
route-target import 100:1
PE1#sh run | in ip route vrf
ip route vrf vpn 1.1.1.1 255.255.255.255 192.168.1.1
!
interface FastEthernet0/0
ip vrf forwarding vpn
ip address 192.168.1.2 255.255.255.252
在PE1上配置MP-IBGP
PE1#sh run | be router bgp
router bgp 100
bgp log-neighbor-changes
no bgp default ipv4-unicast
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
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
network 192.168.1.0 mask 255.255.255.252
redistribute static metric 1
exit-address-family
在PE2也作类似配置。
