EIGRP(Enhanced Interior Gateway Routing Protocol) Understanding EIGRP Features and Advantages■ DUAL -DUAL is one of the main features of EIGRP. It diffuses the routing computation over multiple routers. A more detailed discussion of DUAL is provided in the section “Components of EIGRP.” ■ Loop-free networks -The DUAL algorithm is used to ensure a loop-free network. The calculation of an FS means that the backup route is downstream from the rout..
192.168.1.67인 ip packet이 router로 전송 되는 시나리오 192.168.1.67인 ip packet이 router로 전송 되는 시나리오 192.168.1.0 is subnetted, 3 subnets o 192.168.1.16/28 [110/1800] via 172.16.1.1, 00:05:17, Serial 0 C 192.168.1.32/28 is directly connected, Ethernet 0 o 192.168.1.64/28 [110/10] via 192.168.1.33, 00:05:17, Ethernet 0 prefix 길이가 28이고 3개 항목의 처음 24비트는 모두 일치하기 때문에 router는 숫자 67의 처음 4 bit와 일치하는 항목을 routing table에서 찾아야 한다. 마지막 4bit의 일치 여부는 중요하지 않다. 즉 0100xx..
Static Routing & Default Routing Static routing Router(config)#ip route network [mask] {address | intface} [distance] ex)Router(config)#ip route 192.168.0.0 255.255.0.0 10.10.10.0 Default routing ex)Router(config)#ip default-network 192.168.0.0 ex)Router(config)#ip route 0.0.0.0 0.0.0.0 192.168.0.1 Default routing 조건 1. Ip default-network 뒤에 오는 네트워크 주소는 항상 class를 맞춰 주어야 하나. 2. RIP에서 default network를 구성하는 경우 Ip default-network 뒤..
