Hello Juan:
You would think not. Just for testing, why not set the default-gateway in opposite directions. So, set it for .1 on the .2 device and .2 on the .1 device. Mike From: Juan C. Crespo R.

Smith - Adhost Cc: [email protected] Subject: Re: [c-nsp] Catalyst 2950G Trunking Issue Michael, the vlan interface on each switch are different (10.0.0.1, 10.0.0.2), the default-gateway is set to 10.0.0.3, but into my knowledge, there is no need to use one router to allow the ping on each one, if they are on the same subnet. Michael K. Smith - Adhost escribió: Hello: Okay, top posting. J Is the default gateway reachable by both devices? I didn't see an ARP entry that looked like a default gateway, given that only the remote-switch MAC Address. If you have the same address for both that's either one of the switches or is not reachable then that may cause issues. Mike From: Juan C. Crespo R.
