Hi Krishna,

Please refer attached file for the configuration.

Im facing problem with all the server farms.

thanks

Hi Mohamad,

The configuration looks good. Can you please share the output of 'show serverfarm'

Krishna

Hi Krishna,

#sh serverfarm

   serverfarm           type      rservers predictor          current conns
  +--------------------+---------+--------+------------------+---------------
   SF_KALAM
                        HOST      2        ROUNDROBIN         0
   SF_Kalam1
                        HOST      1        ROUNDROBIN         0
   SF_Kalam2
                        HOST      1        ROUNDROBIN         0
   SF_Kalam3
                        HOST      1        ROUNDROBIN         0

Need help/advise regarding routing to make this method working.

When I change server gateway to ace server vlan interface, my server cannot communicate with other vlans. From context, I can ping server vlan and other vlans.

*Core interface -172.16.36.254 (server vlan),172.19.30.254(client vlan).

*Lb interface - 172.16.36.70, 172.19.30.65

*Real Server ip is using default gateway 172.16.36.70

Routing what I have done:

CORE- ip route 172.16.36.0 255.255.255.0 172.16.36.70
      ip route 172.19.30.0 255.255.255.0 172.19.30.65

LB- ip route 0.0.0.0 0.0.0.0 172.19.30.254

Can someone help me to verify this?

Thanks

Additional info:

there is a result of show conn:

conn-id    np dir proto vlan source                destination           state
----------+--+---+-----+----+---------------------+---------------------+------+
1679012    1  in  TCP   301  172.16.30.215:60714   172.19.30.62:80       SYNSEEN

Hi Mohamad,

What is the default gateway configured for the Load Balancer. Where is the IP 172.16.36.254 is configured. Can you please change the default gateway to 172.13.30.x subnet IP.

From the output I see that Sync packets are never completing the 3-way handshake.

Krishna

Hi Krishna,

IP 172.16.36.254 is at Core interface, so do I need to change the route to 172.19.30.254 (interface at core)? Already done that but nothing happen.

Info:

*Core interface -172.16.36.254 (server vlan),172.19.30.254(client vlan).

*Lb interface - 172.16.36.70, 172.19.30.65

*Real Server ip is using default gateway 172.16.36.70

After I reboot the real server, it cannot communicate with other vlan after changing it gateway to 172.16.36.70.It seems have routing issue. what would you suggest the routing at core/LB?

thanks

Add this config as well:

policy-map multi-match int36
  class VS_Kalam1
    loadbalance vip inservice
    loadbalance policy VS_Kalam1-l7slb
    loadbalance vip icmp-reply active
  class VS_Kalam2
    loadbalance vip inservice
    loadbalance policy VS_Kalam2-l7slb
    loadbalance vip icmp-reply active
  class VS_Kalam3
    loadbalance vip inservice
    loadbalance policy VS_Kalam3-l7slb
    loadbalance vip icmp-reply active
  class VS_Kalam
    loadbalance vip inservice
    loadbalance policy VS_Kalam-l7slb
    loadbalance vip icmp-reply active

interface vlan 36
  description "Server Side"
  ip address 172.16.36.70 255.255.255.0
  access-group input INBOUND
  service-policy input int36
  service-policy input management_vlan
  no shutdown
