EIGRP - Filtering Administrative Distance
Diinginkan IP Loopback R1 tidak lagi dimunculkan dalam routing tabel R3, yakni
dengan di set nilai administrative distance nya menjadi 255
Bikin access list di R3
R3(config)#access-list 2 permit 1.1.1.1
kemudian set distance 1.1.1.1 menjadi 255 di EIGRP serta masukan nilai 2 nya
R3(config)#router eigrp 1
R3(config-router)#distance 255 0.0.0.0 255.255.255.255 2
verfikasi di R3
R3(config-router)#do sh ip route
Codes: L - local, C - connected, S - static, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2
i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
ia - IS-IS inter area, * - candidate default, U - per-user static route
o - ODR, P - periodic downloaded static route, H - NHRP, l - LISP
a - application route
+ - replicated route, % - next hop override
Gateway of last resort is not set
2.0.0.0/32 is subnetted, 1 subnets
D 2.2.2.2 [90/409600] via 23.23.23.2, 00:00:06, Ethernet0/0
3.0.0.0/32 is subnetted, 1 subnets
C 3.3.3.3 is directly connected, Loopback0
12.0.0.0/24 is subnetted, 1 subnets
D 12.12.12.0 [90/2195456] via 23.23.23.2, 00:00:06, Ethernet0/0
23.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
C 23.23.23.0/24 is directly connected, Ethernet0/0
L 23.23.23.3/32 is directly connected, Ethernet0/0
Mantabb akhirnya di R3 ip loopback R1 tidak ditampilkan
