Cisco Configuration Error Issue

Hello Experts,

Can someone please take a look at the attached configuration at let me know why I'm unable to ping ALS1 40.1.1.3 from ALS2, 40.1.1.4?

I need a fresh pair of eyes to look at this - going nuts

 

I have attached the configs and topology.

Cheers

If you use cisco IOU for testing, it does not support ISL trunk.

Kirill,

 

I discovered IOU didn't support ISL after about 8 hours - I was nearly going out of mind trying to figure it. I thought I was doing something wrong.

 

Thanks

Thanks for responding.

 

The problem was with GNS3
