Load balancing voice vlans between two Cisco4506

jasonkwang · ‎10-11-2006

I have try load balancing different voice vlans on 2 Cisco 4506 using hSRP and it don't work. Wonder any one have try out this ! Or is it that voice does not support asymmetric routing

HSRP forwards all IP traffic. I can't help you without configuration details.

Please post your configuration.

Hi

What exactly is your topology?

If you have two 4506s as a core or distribution layer, with multiple access switches attached... and are trying to set each 4506 as the HSRP DG for alternate subnets this will work to load balance the traffic, but only if your STP topology mirrors your Layer 3/HSRP setup.

Basically what this comes down to is that if 4506-A is the HSRP active member for VLAN1, it should also be the STP root for VLAN1. Likewise, if 4506-B is the active HSRP member for VLAN2, then is should be the STP root for VLAN2.

Hi

It is simple as you configure HSRP for data vlans.

for eg:

on u r first 4506 try this

interface vlan 2

ip address 10.1.1.2 255.255.255.0

standby 1 ip 10.1.1.1

standby 1 priority 100

standby 1 preempt

and on second

interface vlan 2

ip address 10.1.1.3 255.255.255.0

standby 1 ip 10.1.1.1

standby 1 priority 150

standby 1 preempt

and one thing i would suggest is that is ur both switches are core.if they are core make sure that u configure one as root for the vlans and second as secondry root for the vlans.

Thanks
