【正文】 this stops the query from spreading in that branch of the work. 在 HubandSpoke 拓?fù)渲械母潞筒樵? You do not want to use these paths! EIGRP Stub ? The EIGRP stub routing feature improves work stability, reduces resource utilization, and simplifies remote router (spoke) configuration. ? Stub routing is monly used in a hubandspoke topology. ? A stub router sends a special peer information packet to all neighboring routers to report its status as a stub router. ? A neighbor that receives a packet informing it of the stub status does not query the stub router for any routes. 配置 EIGRP Stub ? receiveonly: Prevents the stub from sending any type of route. ? connected: Permits stub to send connected routes (may still need to redistribute). ? static: Permits stub to send static routes (must still redistribute). ? summary: Permits stub to send summary routes. ? Default is connected and summary. eigrp stub [receiveonly|connected|static|summary] Router(configrouter) 限制查詢和更新 : EIGRP Stub 示例 : eigrp stub 參數(shù) If stub connected is configured: ?

B will advertise ? B will not advertise , , or If stub receiveonly is configured: ? B will not advertise anything to A, so A needs to have a static route to the works behind B to reach them. EIGRP 查詢進(jìn)程陷入主動 ? The router has to get all the replies from the neighbors with an outstanding query before the router calculates the successor information. ? If any neighbor fails to reply to the query within 3 minutes by default, the route is SIA, and the router resets the neighbor relationship with the neighbor that fails to reply. SIA：陷于主動狀態(tài) Before Router A resets relationship to router B when the normal active timer expires. However, the problem is the link between router B and C. After Router A sends an SIAQuery at half of the normal active timer. Router B acknowledges the query there by keeping the relationship up. 完美關(guān)閉 結(jié)束語 謝謝！ 。 each participating neighbor must have same key configured. MD5 認(rèn)證 EIGRP MD5 authentication: ? Router generates a message digest, or hash, of the key, key ID, and message. ? EIGRP allows keys to be managed using key chains. ? Specify key ID (number), key, and lifetime of key. ?
