Dear Sir,

I have a pair of 11501 and need to load balance a pair of web/mail servers. Below is the reloated configuration on one 11501.

interface e3

bridge vlan 30

interface e8


!************************** CIRCUIT **************************

circuit VLAN10

ip address

ip virtual-router 10 priority 120 preempt

ip redundant-interface 10

ip redundant-vip 10

circuit VLAN30

ip address

ip virtual-router 30 priority 110

ip redundant-interface 30

!************************** SERVICE **************************

service PISWEBP01

redundant-index 31

ip address


service PISWEBP02

redundant-index 32

ip address


!*************************** OWNER ***************************

owner PIS_PISWEBP0102

content PIS-DNS-VIP-1

vip address

port 53

protocol tcp

redundant-index 35

add service PISWEBP01

add service PISWEBP02


content PIS-HTTP-VIP-1

vip address

port 80

protocol tcp

redundant-index 33

add service PISWEBP01

add service PISWEBP02


content PIS-SMTP-VIP-1

vip address

port 25

protocol tcp

redundant-index 34

add service PISWEBP01

add service PISWEBP02


Vlan10 is the external interface and web servers are connected to vlan 30.

We found that all none of the below works.

1. web

2. DNS lookup


Any idea?

Thank you!

1. What does the "show virtual-routers" command output says? Is the same CSS active for both virtual routers (front and back)?

2. Where do clients reside? Do you have a default route on CSS?

3. What does the "show service" command output says?

Best regards,
