====== Cisco : Redistribution route ======
Redistribusi rute adalah proses berbagi rute yang dipelajari dari satu protokol routing ke protokol routing lainnya. Ini penting untuk menciptakan jaringan yang terpadu di mana beberapa protokol routing dapat bekerja bersama.

===== Syntax =====

Sintaks dasar untuk meredistribusi rute di Cisco:

<code>
router <nama-protokol>
 redistribute <protokol-sumber> [metric <nilai>] [subnet]
 exit
</code>

  * nama-protokol: Nama protokol routing yang sedang dikonfigurasi (misalnya, RIP, OSPF, EIGRP).
  * protokol-sumber: Protokol routing yang rute-nya ingin didistribusikan (misalnya, static, connected, EIGRP).
  * metric: Opsional. Mengizinkan Anda untuk mengubah metrik default untuk rute yang didistribusikan.
  * subnet: Opsional. Mengizinkan Anda untuk menentukan subnet spesifik yang akan didistribusikan.

Contoh:

Mari redistribusikan rute statis ke EIGRP:

<code>
router eigrp 100
 redistribute static metric 255
 exit
</code>
Perintah ini mendistribusikan semua rute statis ke EIGRP dengan metrik 255.

Table routing pada R0 tersimpan rute kesemua network akan tetapi pada R21 hanya mendapatkan advertaise rute ospf dari R0. Untuk R0 dapat membagikan table routing ke protocol lain (misal eigrp) maka kita perlu mendistribusikan eigrp pada ospf. DST…

==== Redistrubute Conntected, Static,dan EIGRP ke table routing OSPF. ====
<code js>
R0(config)#router ospf 1
R0(config-router)#redistribute connected subnet
R0(config-router)#redistribute static subnets 
R0(config-router)#redistribute eigrp 1 subnets 
</code>
<WRAP center round info 100%>
tanpa ''%%subnets%%'' redistribution hanya mendukung classfull subnets. Dengan ''%%subnets%%'' redistribution mendukung vlsm walaupun pada percobaan ini subnets classfull.
</WRAP>

==== Redistrubute Static, EIGRP ke table routing EIGRP. ==
<code js>
R0(config)#router eigrp 1
R0(config-router)#redistribute ospf 1 metric 10000 100 255 1 1500
R0(config-router)#redistribute static metric 10000 100 255 1 1500
R0(config-router)#redistribute connected metric 10000 100 255 1 1500
</code>
<WRAP center round info 100%>
Untuk redistribute OSPF ke EIGRP pastikan anda menentukan metricnya. Terkadang route tidak terdistribusikan apabila anda tidak menentukanya.
