private vlan and HSRP

[hetao]

Hi, guys. I have a question about Private Vlan and HSRP implement. In my network topology, there are 2 switch 6509 as core switches and Internet outlet. There are a 3750 as a distribute swtich, and 3550 as a access swtich. the topology is as below:

| |

7609----7609

| |

\ /

3750

|

3550

|

servers

Now there are some Server will connect to 3550, and 3750 and 3550 will be treated as Layer 2 switch, that is these servers's default gateway will be on vlan interface on 7609, and I have configured HSRP between the vlan on 2 6509. My question is how to implement private vlan on 3550 with HSRP on 7609, so that these servers can have redundancy gateway, and be kept isolated between other servers.

It looks like the 3550 do not support private VLAN.

Did you configure the VLAN trunking between 7609, 3750 and 3550 ? Once we enable the VLAN trunking then the server can plug to the assigned VLAN and communicate to the 7609 via the trunk w/o interference w/ other VLAN. However, you have to enable the VLAN routing at 7609 to make it able to connect to other VLAN user if you want.

Hope this helps.
