RE: Extended ACL to permit GRE traffic..

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.
