Hi Eveyybody,
I have two 3750s interconnected via L3 port channel (second switch will be placed on WAN after finished additional config).
I have RIP enabled for subnets on both sides, everything seems to be working perfectly fine, routing is OK...etc.
The problem I have been experiencing is:
1. Let's say VLAN1 is 10.0.0.1/24 (on switch_1) and VLAN1 L3 interface is not present on switch_2.
I can get from hosts on both sides to each other, that is not an issue, but when TRYING TO get to any clients on VLAN 1 (only, work when vlan 2...etc.) from switch_2 (itself), IT ALWYAS times out!?!
I am attaching configuration files from both switches for your review, plus routing tables. Please let me know if you need more info.
Any help with this issue will be highly appreciated!
Best regards,
Ed
