mpls范例

小弟才疏学浅..把之前公司学到的一点东西拿出来献丑

以下是在pe router一定要有的设定

ip vrf aaa ---aaa就是客户名称

rd 1234:1 ---rd是mbgp在交换routing用的

route-target eXPort 1234:1

route-target import 1234:1

ip cef ---一定要下..不下打死不会通

interface FastEthernet1/0

ip address xxxx

full-duplex

tag-switching mtu 1530 ----接到p router一定要下此行..因为加了tag mtu 会变大

tag-switching ip ----让interface知道上面有跑加了tag 的封包

interface serial 0/0

ip address xxxx

ip vrf fowarding aaa ---上下车的interface要加上tag要打此行

--以下都是再定义mbgp..所有mpls的routing都是用mbgp交换的---

router bgp 1234

no synchronization

no bgp default ipv4-unicast

bgp log-neighbor-changes

neighbor MPLS-PEER peer-group ---MPLS-PEER这个字符串是自订的名称

neighbor MPLS-PEER remote-as 1234

neighbor MPLS-PEER update-source Loopback0

neighbor MPLS-PEER activate

neighbor 1.1.1.1peer-group MPLS-PEER ....由于是要靠ibgp交换.所以要fully mesh...有几颗pe就要输入几颗pe的 ip

neighbor 2.2.2.2 peer-group MPLS-PEER

neighbor 3.3.3.3 peer-group MPLS-PEER

neighbor 4.4.4.4 peer-group MPLS-PEER

no auto-summary

address-family ipv4 vrf aaa

redistribute connected

redistribute static

no auto-summary

no synchronization

exit-address-family

address-family vpnv4

neighbor 1.1.1.1 activate

neighbor 1.1.1.1 send-community extended

neighbor 2.2.2.2 activate

neighbor 2.2.2.2 send-community extended

neighbor 3.3.3.3 activate

neighbor 3.3.3.3 send-community extended

neighbor 4.4.4.4 activate

neighbor 4.4.4.4 send-community extended

ip route vrf aaa 192.168.181.0 255.255.255.0 192.168.1.6 ---要下车的default route..在此范例中要往serial 0/0丢的才对

至于p router...上面跑的就只有ospf啦..
