HARI 3 Sesi 1 MUTUAL REDISTRIBUTION

************************

Lab 1. Mutual Redistribution
Lab 2. Mutual Redistribution – 2 titik
Lab 3. Mutual Redistribution – Route Tagging

*************************

Percobaan lab untuk saling meredistribute antar routing protokol.

LAB 1 MUTUAL REDISTRIBUTION

Scenario :

Mutual redistribusi antara RIP – OSPF – EIGRP dan RIP lagi.

Note :

ke Eigrp : issue metric K1 – K5 ( metric 1 1 1 1 1)

ke OSPF issue Subnet (area) command subnets

ke RIP isu metric/Hop ( metric 1)

Verifikasi : 

…Terlihat terjadi looping , R2 ( RIP ) dan R3 ( OSPF) , router memilih yg nilai AD nya paling kecil. sehingga paket tidak

akan memilih RIP (120), melainkan kembali lagi ke OSPF(110), demikian seterusnya
sehingga terjadi looping
