SO SÁNH DISTANCE VECTOR VÀ LINK- STATE: Distance Vector và LinkState đều là các giao thức định tuyến động (Dynamic Routing Protocol) cấu hình ... trao đổi các topology bên cạnh với nhau update vào routing table, tính giải thuật đường đi lớnnhất và chiếm nhiều bộ nhớ (link stateroutingprotocols OSPF, NLSP, IS-IS). A, khi Host ... trong routing table của Router1 sẽ không có route nào đến mạng B (10.11.0.0/16). Để giải quyết vấn đề này, dùng static routing hoặc dùng các routing hỗ trợ VLSM. Khi này thì cần phải có các routing...

Disconnect West router: 09:26:26:%STANDBY-6-STATECHANGE: Standby: 0: FastEthernet0/0 state Active-> ... they are both connected to the same network. A routing protocol is not needed. Each router has knowledge of all networks in the network. IP Routing will need to be enabled on all routers. ...

Future versions of EIGRP will peer based onrouter ID, rather than per link, cutting down on resource use when you have parallel links.Router ... enable RIP and configure a networkstatement for the router interfaces that will be running RIP. RIP version 1 is a classful routing protocol, and thus all links within the RIP domain must use ... RIPv1 is best used on links with only RIP devices, since its advertisementsare sent as broadcasts. If it were used on a LAN link with hosts as well as a neighbor router onthe link, the hosts would...
