1、CCNP之OSPF實(shí)驗(yàn)案例實(shí)驗(yàn)要求：1、總部和分部之間通過幀中繼實(shí)現(xiàn)互訪，協(xié)議要求采用OSPF。要求幀中繼不能動(dòng)態(tài)獲取映射，也不能靜態(tài)配置映射2、配置好OSPF協(xié)議，驗(yàn)證鄰居建立3、確保整個(gè)內(nèi)網(wǎng)全網(wǎng)可達(dá)4、確保骨干區(qū)域高安全性5、盡量減少網(wǎng)關(guān)路由表?xiàng)l目6、R1、R3、R9性能不足，盡量減少其路由條目7、確保總部和分部都只通過自己的ISP上網(wǎng)8、不能出現(xiàn)主機(jī)路由實(shí)驗(yàn)拓?fù)洌簩?shí)驗(yàn)步驟：1、幀中繼的配置：由于不能配置幀中繼動(dòng)態(tài)和靜態(tài)映射，所以只能采用點(diǎn)對(duì)點(diǎn)子接口模式進(jìn)行配置，在接口下聲明自己的DLCI。其中R5的Route-ID是1.1.1.1，R6的Route-ID是2.2.2.2
2、。由于是點(diǎn)對(duì)點(diǎn)連接，所以不存在DR和BDR。FR-SW：FR-SW(config)#frame-relayswitchingFR-SW(config)#ints0/0FR-SW(config)#noshutFR-SW(config-if)#encapsulationframe-relayFR-SW(config-if)#clockrate64000FR-SW(config-if)#frame-relayintf-typedceFR-SW(config-if)#frame-relayroute102ints0/1201FR-SW(config)#ints0/1FR-SW(con
