BGP path manipulation using MED

pada posting ini kita akan melihat bagaimana kita manipulate path bgp...
pastikan dulu intial config ping ke masing-masing router bisa berjalan...dan tambahkan protocol IGP di iBGP supaya BGP bisa up...
ada soal seperti ini, ***konfigurasi bagaimana AS#12 ke AS#6 menggunakan R1 sebagai exit point...anda hanya bisa melakukan confignya di R4 menggunakan outbound direction MED....***
berikut confignya...

EEM Applet Script configuration

pada posting ini saya akan mencontohkan fungsi dari IOS EEM--Embedded Event Manger, jika kita melakukan shutdown pada interface lo0, dengan fungsi EEM ini, interface lo0 akan bisa dengan automatically up kembali....
mari kita lihat example dari EEM....

di R1 kita buat dulu interface lo0, lalu kita ketik EEM commandnya :
R1#conf t
R1(config)#inter lo0

R1(config-if)#ip add 1.1.1.1 255

dari sesi diatas dapat terlihat ketika interface lo0 di shutdown, maka interface lo0 tersebut akan otomatis no shut sendiri karena telah menggunakan applet EEM di Router ini...

Using Kron for automatic backup config your router

pada posting ini, saya akan mencontohkan cara menggunakan automatic backup dengan archive dan Kron...

Menggunakan Archive :
pertama yang harus ada adalah tftpserver, bisa menggunakan 3CDaemon atau tftp32, pastikan tftp ini aktif selalu...

lalu kita coba cara backup config menggunakan archive....
R1#conf t
R1(config)#archive
R1(config-archive)#path tftp://10.10.10.100/backup-cfg ***untuk menempatkan config file di IP yang tertera dan nama backup filenya***
R1(config-archive)#time-period 1440 ***simpan dalam waktu 24jam***
R1(config-archive)#write-memory
R1(config-archive)#end
R1#
R1#write
Building configuration... ***perhatikan waktu write-memory***
[OK]!!
R1#
R1#write
Building configuration...
[OK]!!

waktu kita ketik write-memory, akan tersimpan file didalam directory di tftpserver yang sedang aktif....

Sekarang menggunakan Kron:
R1#conf t
R1(config)#kron-policy
R1(config-kron-policy)#kron policy-list netx
R1(config-kron-policy)#cli sh running-config | redirect tftp://10.10.10.100/netxbackup-cfg
R1(config-kron-policy)#exit
R1(config)#kron occurence netx-kron at 10:00 recurring
R1(config-kron-occurence)#policy-list netx
R1(config-kron-occurence)#end
R1# sh kron schedule
Kron Occurence Schedule
netx-kron incative. will run again in 0 days 18:16:48 at 10:00 on

R1#cloct set 9:59:30 31 Dec 2011
R1#sh kron schedule
Kron Occurence Schedule
netx-kron incative. will run again in 0 days 00:00:29 at 10:00 on

R1#sh kron schedule
Kron Occurence Schedule
netx-kron incative. will run again in 0 days 00:00:01 at 10:00 on

R1#sh kron schedule
Kron Occurence Schedule
netx-kron active. will run again in 0 days 23:59:58 at 10:00 on

lalu kita lihat di tftp akan ada tambahan backup file dengan nama netxbackup-cfg di directory tftpserver anda....
silahkan anda buka file tersebut dengan notepad atau wordpad..

sekian untuk posting ini...

RSTP, MST Configuration

Pertama gunakan EIGRP AS 2003, dan pastikan walker1 dan walker2 bisa ping..lalu kita lanjut ke walker1:

hostname walker1
!
interface Vlan1
 no ip address
 shutdown
!
interface Vlan192
! ip address 172.16.192.16 255.255.255.0

Configurasi VTP di walker1

walker1#vlan database
walker1(vlan)#vtp domain walker
walker1(vlan)#vtp server
walker1(vlan)#vtp password psv2

lanjut ke konfigurasi VLAN port :

interface FastEthernet0/3
 switchport access vlan 300
! assigned to VLAN 300
 switchport mode access
 spanning-tree portfast
! Portfast used in 802.1w
 no ip address
!
interface FastEthernet0/5
 switchport access vlan 100
! assigned to VLAN 100
 switchport mode access
spanning-tree portfast
! Portfast used in 802.1w
 no ip address
!
interface FastEthernet0/8
 switchport access vlan 100
! assigned to VLAN 100
 switchport mode access
 spanning-tree portfast
! Portfast used in 802.1w
 no ip address

dilanjutkan dengan configurasi portfast :

walker1(config)#interface range fastEthernet 0/10 - 15
walker1(config-if-range)#switchport mode access
walker1(config-if-range)#switchport access vlan 20
walker1(config-if-range)#spanning-tree portfast
%Warning: portfast should only be enabled on ports connected to a single
 host. Connecting hubs, concentrators, switches, bridges, etc... to this
 interface  when portfast is enabled, can cause temporary bridging loops.
 Use with CAUTION
%Portfast will be configured in 6 interfaces due to the range command
 but will only have effect when the interfaces are in a non-trunking mode.
walker1(config-if-range)#exit

untuk memverifikasi VLAN dan VTP status :

walker1#show vlan
VLAN Name                             Status    Ports

kita bisa lihat kalo interface C1 atau C2 down, melalui VRRP ini traffic tetap bisa lewat, asalkan salah satu router C1 atau C2 masih tetap up sebagai master...

Video Zone-Based Firewall Configuration

di video ini, akan menampilkan zone inside dan outside,
INSIDE zone, link antara R2 dan R1dimana fa0/0-R2 (vlan 2, 10.0.0.2/24) dan fa0/0-R1 10.0.0.1/24
OUTSIDE zone, link antara R3 dan R2 dimana fa0/1-R2 23.0.0.2/24 dan fa0/1-R3 23.0.0.3/24....
pertama membuat class-map CMAP-1...
match protocol tcp, icmp dan udp...
kita buat policy-map PMAP-1, didalamnya kita assign class-map CMAP-1
kita inspect dan kita rate-limit 8000bits...
lalu ditambahkan zone-pair sec inside-to-outside source inside destination outside
masukkan service-policy type inspect PMAP-1...
kita tes ping...
lalu untuk melihat policy-map ini, kita gunakan show policy-map type inspect zone-pair sessions
akan terlihat class-map CMAP-1, match protocol ICMP, akan ada traffic packet yang lewat...
