靜態(tài)LSP配置實(shí)驗(yàn)

靜態(tài)LSP配置實(shí)驗(yàn)組網(wǎng)需求如圖所示，LSR_1、LSR_2、LSR_3為MPLS骨干網(wǎng)設(shè)備。要求在骨干網(wǎng)上創(chuàng)建穩(wěn)定的公網(wǎng)隧道來(lái)承載L2VPN或L3VPN業(yè)務(wù)。配置思路配置靜態(tài)LSP，可以實(shí)現(xiàn)此需求。按要求需配置兩條靜態(tài)LSP：LSR_1到LSR_3的路徑為L(zhǎng)SP1，LSR_1為Ingress，LSR_2為Transit，LSR_3為Egress；LSR_3到LSR_1的路徑為L(zhǎng)SP2，LSR_3為Ingress，LSR_2為Transit，LSR_1為Egress。采用如下的配置思路：在LSR上配置OSPF，實(shí)現(xiàn)骨干網(wǎng)的IP連通性。2.在LSR上配置MPLS功能，這是實(shí)現(xiàn)在骨干網(wǎng)上創(chuàng)建公網(wǎng)隧道的前提。3.由于網(wǎng)絡(luò)拓?fù)浣Y(jié)構(gòu)簡(jiǎn)單并且穩(wěn)定，且需創(chuàng)建穩(wěn)定的公網(wǎng)隧道來(lái)承載L2VPN或L3VPN業(yè)務(wù)，因此配置靜態(tài)LSP。為了實(shí)現(xiàn)這一步，需進(jìn)行以下操作。a.在Ingress配置此LSP的目的地址、下一跳和出標(biāo)簽的值。b.在Transit配置此LSP的入接口、與上一節(jié)點(diǎn)出標(biāo)簽相等的入標(biāo)簽的值、對(duì)應(yīng)的下一跳和出標(biāo)簽的值。c.在Egress配置此LSP的入接口、與上一節(jié)點(diǎn)出標(biāo)簽相等的入標(biāo)簽的值。操作步驟1.在交換機(jī)上創(chuàng)建VLAN、VLANIF接口，配置VLANIF接口的IP地址，并將相應(yīng)的物理接口加入到VLAN#配置LSR_1。LSR_2和LSR_3的配置與LSR_1類似，不再贅述。<HUAWEI>system-view[HUAWEI]sysnameLSR_1[LSR_1]interfaceloopback1[LSR_1-LoopBack1]ipaddress32[LSR_1-LoopBack1]quit[LSR_1]vlanbatch100[LSR_1]interfacevlanif100[LSR_1-Vlanif100]ipaddress24[LSR_1-Vlanif100]quit[LSR_1]interfacegigabitethernet1/0/1[LSR_1-GigabitEthernet1/0/1]portlink-typetrunk[LSR_1-GigabitEthernet1/0/1]porttrunkallow-passvlan100[LSR_1-GigabitEthernet1/0/1]quit2.配置OSPF協(xié)議發(fā)布各節(jié)點(diǎn)接口所連網(wǎng)段和LSRID的主機(jī)路由#配置LSR_1。[LSR_1]ospf1[LSR_1-ospf-1]area0[LSR_1-ospf-1-area-]network[LSR_1-ospf-1-area-]network55[LSR_1-ospf-1-area-]quit[LSR_1-ospf-1]quit#配置LSR_2。[LSR_2]ospf1[LSR_2-ospf-1]area0[LSR_2-ospf-1-area-]network[LSR_2-ospf-1-area-]network55[LSR_2-ospf-1-area-]network55[LSR_2-ospf-1-area-]quit[LSR_2-ospf-1]quit#配置LSR_3。[LSR_3]ospf1[LSR_3-ospf-1]area0[LSR_3-ospf-1-area-]network[LSR_3-ospf-1-area-]network55[LSR_3-ospf-1-area-]quit[LSR_3-ospf-1]quit#配置完成后，在各節(jié)點(diǎn)上執(zhí)行displayiprouting-table命令，可以看到相互之間都學(xué)到了彼此的路由。3.在各節(jié)點(diǎn)使能MPLS基本功能#配置LSR_1。[LSR_1]mplslsr-id[LSR_1]mpls[LSR_1-mpls]quit#配置LSR_2。[LSR_2]mplslsr-id[LSR_2]mpls[LSR_2-mpls]quit#配置LSR_3。[LSR_3]mplslsr-id[LSR_3]mpls[LSR_3-mpls]quit4.配置各接口的MPLS能力#配置LSR_1。[LSR_1]interfacevlanif100[LSR_1-Vlanif100]mpls[LSR_1-Vlanif100]quit#配置LSR_2。[LSR_2]interfacevlanif100[LSR_2-Vlanif100]mpls[LSR_2-Vlanif100]quit[LSR_2]interfacevlanif200[LSR_2-Vlanif200]mpls[LSR_2-Vlanif200]quit#配置LSR_3。[LSR_3]interfacevlanif200[LSR_3-Vlanif200]mpls[LSR_3-Vlanif200]quit5.創(chuàng)建從LSR_1到LSR_3的靜態(tài)LSP#配置IngressLSR_1。[LSR_1]static-lspingressLSP1destination32nexthopout-label20#配置TransitLSR_2。[LSR_2]static-lsptransitLSP1incoming-interfacevlanif100in-label20nexthopout-label40#配置EgressLSR_3。[LSR_3]static-lspegressLSP1incoming-interfacevlanif200in-label40配置完成后，可在各節(jié)點(diǎn)上用displaymplsstatic-lsp命令查看靜態(tài)LSP的狀態(tài)。LSR_1顯示為例：LSP是單向的，需要再配置LSR_3到LSR_1的靜態(tài)LSP。6.創(chuàng)建從LSR_3到LSR_1靜態(tài)LSP#配置IngressLSR_3。[LSR_3]static-lspingressLSP2destination32nexthopout-label30#配置TransitLSR_2。[LSR_2]static-lsptransitLSP2incoming-interfacevlanif200in-label30nexthopout-label60#配置EgressLSR_1。[LSR_1]static-lspegressLSP2incoming-interfacevlanif100in-label607.檢查配置結(jié)果配置完成后，在各節(jié)點(diǎn)上用displa
