RE: Extended ACL to permit GRE traffic..

Sorry Martin I think you were out of line with your approach! You & some
others who subscribe in this e-mail group need to come down from your
pedestal.

Hi Jit,

I was going for the "teach a man to fish" rather than give him a fish
approach.

So yes, I was trying to help more than simply typing out an answer. I like to
think that CCIE's or people who aspire to be would or should be interested in
the how and why things work as they do rather than just the answer.

Glad you got what you were after.

Martin

Martin, I am not sure whether you're trying to help or just making us guess
what you know????

My understanding was that GRE would be automatically permitted if I permit IP
- that's it.

If that's not the case I was expecting someone to tell me.

Think back to basics;

What is IP?
What is GRE?

How do they work (together?)?

Hi All,

If you create a Extended ACL as;

ip access-list extended TUNNEL
permit ip host 203.208.174.93 host 85.115.65.7

Would this permit GRE traffic - for example?

OR

do I need this to permit GRE;

ip access-list extended TUNNEL
permit gre host 203.208.174.93 host 85.115.65.7

Thank you.
