TAMBAHAN (R3 DAN R4)
R3
R3
interface gi0/1
glbp 1 ip 10.100.100.254
glbp 1 preempt
glbp 1 priority 110
glbp 1 load-balancing round-robin
glbp 1 authentication md5 key-string cisco

R4
interface gi0/1
glbp 1 ip 10.100.100.254
glbp 1 preempt
glbp 1 load-balancing round-robin
glbp 1 authentication md5 key-string cisco

Lalu Verifkasi di R1
Lakukan ping, dan trace dari R1 (10.0.1.1) menuju 10.100.100.100 lewat dari mana?.

 

Nampak bahwa dari R1 menuju ke 10.100.100.100 lewat R3.Sekarng kt iningkan dia leat R4. berikut commadnya

access-list 1 permit host 10.0.1.1
route-map PBRmatch ip address 1
set ip next-hop 10.0.3.1
exit

interface gi0/0
decription ## link to R1##
ip policy route-map PBR

VERIFIKASI DI R1

 

 

 

Nampak bahwa dari 10.0.1.1 menuju 10.100.100.100.254 melewati R4
Verifikasi di R2 , cek packet PBR

 

SKENARIO-2.
bagimana caranya IP loopback R2 (2.2.2.2) menuju 10.100.100.100 melewati R4. Secara default ip lo2 melewati R3.

Begini stepnya.

Konfig di R2
access-list 100 permit ip host 2.2.2.2 host 10.100.100.100
route-map PBR2
match ip address 100
exit

ip local policy route-map PBR2
exit
