I need some insight and direction for some good information about
tunneling between routers. I understand the concept and the idea behind
them, I just can not seem to get them to work. I am not talking about
IPSec tunnels and VPNs. I am talking about the R&S topic listed in the
blueprint that includes tunnel interfaces. I know I need to know these,
but I am having trouble wrapping my arms around the actual
implementation and why and where you put them. I tried the Cisco
document, but it helped only a little. I don't know why I am having so
much trouble with tunnels, but I am.
I want to know things like:
1. Where do you put the source and why?
2. Where do you put the destination and why
3. When do you assign an IP address to the tunnel?
4. Does the path show up in the routing table at each end? If not, how
does the router know where to send the packets to?
5. What does the tunnel simulate; a Layer 2 connection or a Layer 3
connection.
6. etc...
So many questions. Can someone please show me the light?
Thanks for any help,
-Stephen
