Hi guys,
I am stuck. I've spent 3 evenings trying to find out why my L3 routing not working on 3750.
What I've done so far is:
1. no ip routing and then ip routing
2. write erase and reload, no ip routing-write erase-roload- ip routing
3. shut no shut all respective ports
4. updating IOS to C3750-IPSERVICESK9-M, Version 12.2(55)SE and previous one was ipbase 12.2 (4.) SE
5. increasing MTU to jumbo
6. Only one thing I can't get rid of sysmet mtu routing 1500. I does except no command but line stays anyway
7. sdm prefer ip routing - is enabled
8. I am able to ping end hosts respective gateways but can't ping between SVIs
9. outpot of sh ver, sh run, sh sdm prefer, sh cdp neigh, sh ip route are attached below
10. I can replicate this in Packet Tracer without any problems but with my physical lab where I've got 2x3750 same issue for both switches.
My topology is so streigh forward
