Hybrid замчлалын протокол
EIGRP – Enhanced Interior Gateway Routing Protocol нь Сиско компаний өмчийн distance-vector protocol суурьтай link-state шинжийг агуулсан протокол юм.
EIGRP – ын онцлогууд:• Зөвхөн хөрш рүүгээ замын мэдээлэл дамжуулдаг – DV• 3 хүснэгт үүсгэдэг - LS• Fast convergence• Partial updates• Multiple network layer support – IP, IPX, APPLE TALKUse of multicast and unicast communication• Variable-length subnet masking (VLSM) support - CLASSLESS• Auto-summarization

EIRGP ажиллагаа(3)Router C-ийн хүснэгт:
EIGRP метрик тооцоололт (1)
EIGRP нь дараах параметруудыг ашиглан метрикээ тооцоолдог.
Параметр бүрт тооцоололтонд ашиглагдах эсэхээс хамаарч k1, k2, k3, k4, k5 утгуудыг олгодог
◦ Дефаултаар K1 (bandwidth) = 1, K3 (delay) = 1 ◦ K2 (load), K4 (reliability), K5 (MTU) = 0.
K утгуудыг өөрчлөх боломжтой:Router(config-router)# metric weights tos k1 k2 k3 k4 k5
Парамертуудыг шалгах команд: Router#show interface
EIGRP метрик тооцоололт (2)
Slowest bandwidth:
Plus the sum of the delays
EIGRP метрик тооцоололт (3) Bandwidth = 10,000,000 / 1024 = 9765 * 256 = 2499840
EIGRP метрик тооцоололт (4) Delay = 20,000 / 10 + (100 / 10) * 256 = 514560
EIGRP метрик тооцоололт (5) EIGRP Metric = 2499840 + 514560 = 3014400
