Multilayer switching

mumpung sambil nunggu donlotan ios yang baru posting-posting lagi ah

kali ini akan posting multilayer switch

ini topologi nya sedikit perkembangan dan perubahan dikit dari yang udah ada
topologi ini memakai IOS c3640-is-mz.124-16.bin untuk tiap-tiap switch

konfigurasinya bisa di liat di
http://sioduy.100webspace.net/Multilayer%20Switching/

seputar komputerku

Komputer butut tapi masih lumayan buat emulasi router
jalan di atas prosesor SEMPRON 64 Tm 2800+ 1600Mhz clockspeed
dengan memory DDR1 2 GB lumayan buat jalanin 7 emulasi router cisco 3640 series untuk jalanin BGP IPv6 di GNS3 meskipun akhirnya hampir ga kuat jalaninnya
peer sering down, sering kehilangan tabel routing nya karena prosesor uda 100% bahkan sepertinya mo meledak. pernah kepikiran untuk export file .net GNS3 ke dynagen di FreeBSD 7.1 AMD64.

BGP IPv6 Configuration

konfigurasi BGP IPv6 dari topologi sebelumnya
IOS yang digunakan adalah c3640-jk9s-mz.124-16.bin
bila ada kesalahan atau tuning konfigurasi mohon untuk dikomentari

BGP IPv6 Verification and Testing

Mari kita lanjutkan untuk melihat hasil dari konfigurasi topologi pada postingan yang lalu ada beberapa tambahan pada topologi di atas yakni saya menambahkan network 2001:d30:67::1/64 untuk di advertise oleh R0

R3#show ip bgp ipv6 un neighbors 2001:d31:77::3 advertised-routes

BGP routing table entry for 2001:D32:2::/64, version 8

mari kita coba ping ke salah satu network yang sudah di advertise

R0#ping ipv6 2001:5c2:2::1 source 2001:d30:67::1

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 2001:5C2:2::1, timeout is 2 seconds:
Packet sent with a source address of 2001:D30:67::1
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 284/390/628 ms

Alhamdulillah ping nya bisa....

trus coba lagi di traceroute

R0#traceroute ipv6

Target IPv6 address: 2001:5c3:2::1
Source address: 2001:d30:67::1
Insert source routing header? [no]:
Numeric display? [no]:
Timeout in seconds [3]: 4
Probe count [3]:
Minimum Time to Live [1]:
Maximum Time to Live [30]: 5
Priority [0]:

Type escape sequence to abort.
Tracing the route to 2001:5C3:2::1

Alhamdulillah kluar hasilnya

BGP IPv6 with GNS3

Hmm setelah berguru ke Jeremy akhirnya saya sedikit mengerti tentang BGP

kalo gitu langsung to de poin

ini topologi BGP IPv6 pertamaku
karena uda capek ngetiknya kapan-kapan lagi saya posting konfigurasinya

tapi jangan kuatir sekarang saya posting hasil show ip bgp nya

R0#show ip bgp ipv6 unicast

Modern VLAN

sebelumnya saya mohon mangaps dulu menunda posting instalasi OLIVE JUNOS di FReeBSD 7.0 part 2 tapi tutorial install OlIVE JUNOS uda h banyak di google kapan-kapan saya lanjutkan

mari kita lanjutkan topik nya
emang apa bedanya Modern VLAN ama Legacy VLAN ???
mengutip omongannya jeremy cioara #CCIE guru saya :D
katanya kalo Modern VLAN itu ga perlu router lagi buat hubungin network2 di dalam VLAN
katanya udah ga jaman lagi, bottlenecknya ada di jalur trunk ke router
kalo di catalis 3500 uda bisa modern VLAN dan alhamdulillah bisa ku coba di 3640 Series
istilah kerenya adalah SVI aka Switch Virtual Interface
intinya SVI dibuat dengan menambahkan interface VLAN dalam cisco switch

oke sekarang mari kita lihat topologi sederhana di bawah ini
pada topologi sederhana diatas R0 berfungsi sebagai switch sekaligur router untuk menjalan kan NAT dan DHCP Server Switch R1 ngikut Trunk ke R0
port 1 R0 terhubung ke router R3 dan router R3 seolah-olah terhubung ke server


berikut konfiugurasi SVI.net

mari kita jelaskan konfigurasi Switch R0 diatas

untuk mengaktifkan SVI perlu dibuat virtual interface VLAN pada konfigurasi diatas di buat interface Vlan 10 dan Vlan 20

R0#(config)interface Vlan 10
R0#(config)interface Vlan 20

setelah itu create database Vlan biar port pada switch bisa di seting vlan yang kita inginkan

R0#vlan database
R0#(Vlan-database)Vlan 10 name zenislev
R0#(Vlan-database)Vlan 20 name hoshun

pada port 1 bisa dilihat port tersebut memiliki IP address mestinya port switch tidak bisa di beri IP address, untuk mengaktifkan nya cukup dengan 1 perintah

R0#(config)interface f0/1
R0#(config-if)no switchport

dengan perintah tersebut port tersebut dapat di beri IP address bahkan dapat untuk menjalankan routing protokol seperti OSPF,RIP,EIGRP bahkan BGP. Pada posting berikutnya akan saya tunjukkan bahwa port tersebut dapat menjalankan BGP IPv6

kita lanjutkan dengan mengaktifkan DHCP server
untuk mengaktifkan DHCP Server di cisco cukup dengan perintah

R0#(config)service dhcp

kemudian dhcp dapat di konfigurasi seperti pada konfigurasi DHCP Server di atas
yang membedakan DHCP server di FreeBSD/Linux ato yang lainnya adalah untuk range DHCP
di cisco range DHCP di definisikan dengan range IP yang tidak ingin kita otomatiskan

R0#(config)ip dhcp excluded-address 192.168.2.1 192.168.2.129
dengan konfigurasi diatas nantinya range IP DHCP nya dimulai dari 192.168.2.130 - 254

selanjutnya mengaktifkan NAT
untuk ip nat outside di konfigurasikan ke interface f0/1 dan ip nat inside-nya di konfigurasika ke interface Vlan10 dan Vlan20 bisa dilihat pada konfigurasi di atas
kebetulan NAT yang saya gunakan adalah NAT static overload, sebenarnya untuk VLAN 20 ingin saya gunakan untuk NATPOOL tapi karena waktu itu disuruh nganterin ibu jadi tak samakan aja dengan VLAN 10

WOOOwwww !!! 1 Switch bisa untuk VLAN, DHCP Server bahkan jadi Router juga

untuk router R3 yang menghubungkan ke server menggunakan routing OSPF

Legacy VLAN with GNS3

ya setelah lama ga posting sekarang saatnya aktif nulis lagi

kali ini enaknya bikin topik cara bikin Legacy VLAN di cisco. tapi bukan cisco hardware beneran tapi pake GNS3

mari kita lihat contoh topologi sederhana yang saya buat

router R1 dan router R2 dihubungkan dengan frame relay network
R1 terhubung ke port 1 framerelay switch dengan DLCI 101 dan R2 terhubung ke port 2 DLCI 201

routing protokol yang digunakan adalah ospf

berikut dibawah ini konfigurasinya

untuk konfigurasi file legacy_VLAN.net nya

untuk konfigurasi Switch 3 sama dengan konfigurasi Switch 1 da Switch 2

sedangkan untuk User2nya menggunakan konfigurasi ip dhcp
pada testing di atas Cisco 1700 tidak bisa dikonfigurasi ip dhcp nya
