Hello guys i'm new to configuring routing protocols and I'm trying to understand why I keep getting a "destination host unreachable message"when I ping from router to router across a frame-relay cloud or from one host in vlan 40 or 50 to another host in vlan 20 or 30.
Anyone care to share where I should fix my mistake in configuration? Thank you for helping in advance
