R2511AS# -------------------------------------------------------------------------- 分別是P2MP，P2P。兩種網絡類型。 配置完成后可用sh ip os nei ,sh ip os da,等show 命令來查看，sh ip os da 命令是查看OSPF鏈路數據庫。查看數據庫中沒有應該出現得LSA.碰到問題用debug命令來查看在哪里出問題了。 deb ip os pa deb ip pa deb ip os adj 等命令。 ?。?br /> R2511AS#sh ip os in Serial1.10 is up, line PRotocol is up Internet Address 11.1.1.4/24, Area 0 Process ID 1, Router ID 10.0.0.1, Network Type POINT_TO_MULTIPOINT, Cost: 64 Transmit Delay is 1 sec, State POINT_TO_MULTIPOINT, Timer intervals configured, Hello 30, Dead 120, Wait 120, Retransmit 5 Hello due in 00:00:10 Index 1/2, flood queue length 0 Next 0x0(0)/0x0(0) Last flood scan length is 1, maximum is 2 Last flood scan time is 12 msec, maximum is 16 msec Neighbor Count is 2, Adjacent neighbor count is 2 Adjacent with neighbor 11.1.1.3 Adjacent with neighbor 192.168.0.166 Suppress hello for 0 neighbor(s) Serial1.11 is up, line protocol is up Internet Address 12.1.1.1/24, Area 1 Process ID 1, Router ID 10.0.0.1, Network Type POINT_TO_POINT, Cost: 64 Transmit Delay is 1 sec, State POINT_TO_POINT, Timer intervals configured, Hello 10, Dead 40, Wait 40, Retransmit 5 Hello due in 00:00:01 Index 1/1, flood queue length 0 Next 0x0(0)/0x0(0) Last flood scan length is 1, maximum is 4 Last flood scan time is 4 msec, maximum is 8 msec Neighbor Count is 1, Adjacent neighbor count is 1 Adjacent with neighbor 192.168.0.43 Suppress hello for 0 neighbor(s) R2511AS# －－－－－－－－－－－－－－－－－－－－－ sh ip os interface,查看OSPF運行得接口。有助于排錯。 ?。?br /> 注重broadcast參數，假如沒有加此參數，表明NBMA網絡底層不具備廣播能力，這樣將會造成OSPF鄰居建立不成功，無法得到路由。假如沒有此參數，則需要手動建立OSPF的nei. 進入OSPF進程： nei&n
bsp; [nei ip address] 這樣OSPF將以UNICAST方式發送數據包。（OSPF默認是組播數據包，224.0.0.5,所有路由器之間，224.0.0.6DR BDR之間）
