I have two L3 Switches connected via a lacp etherchannel link. Switch 1 is providing inter-vlan routing for 4 vlans (Vlan 10, 11, 15 and 17). The switches are using vlan 20 for their connectivity. They are configured for redundancy using hsrp with Switch 1 being the Primary and 2 the secondary. I have provided for the standby IPs as gateway for the vlans in the DHCP pools.

I have connected the two switches to two ASA in a failover active/standby scenario, with the ASA inside interfaces being on the same vlan 20 the switches are in. The switches and ASAs can ping each other with no problem. The subnets are as follows:

Subsequently, vlan routing now seems to be messed with the hosts only being able to ping the vlan interface of their respective vlan on Switch 1, Nothing else. I cannot for the life of me figure out where I have messed up.

Thanks for the reply. I have enabled ip routing on both switches and pretty much mirrored the config of Switch 1 on Switch 2 except for respective IP addressing. Instead of using static routing, I have gone for ospf for ease of configuration. The config is pretty long, especially for the ASA so I'll attach the config text files, unless you prefer I post then right with the post.

Posting the configs as text files is quite appropriate. I have taken a quick look at the configs. Can you tell us what model of switch this is? Would you post the output of show ip route from both switches and the output of show standby?

I'm using an IOU image 'i86bi-linux-l2-ipbasek9-15.1g.bin'. It was the only one I could find where HSRP and VTP both worked. As for the other outputs, 'show ip route', and 'show standby', see the attached text file. I chose to put all the outputs in a sectioned text file as I was getting an 'The contents of the attachment doesn't match its file type.' error when I tried uploading the individualized output files.

It seems the issue was/is with the IOU image, 'i86bi-linux-l2-adventerprisek9-15.2d'. I've since replaced it with 'i86bi_linux_l2-adventerprisek9-ms' and inter-VLAN routing is working just fine. Vlan 10 and 11 can reach other other including the other vlans, 15 and 17. The image however keeps popping up segmentation faults (segfault) and the devices either stop working or shutdown. I'm looking for another image.

The issue I have now, other than the hunt for a stable L2 image is the connection between the L3 switch and the ASA. What's the best practice, considering the HSRP on the switches and the failover on the ASA? Is it;
