Day 43

1. Your boss asks you to permit GRE on your access list. What do you configure?

2. Keepalives are disabled by default on a GRE tunnel, so the tunnel interface will show up even if the remote side has gone down.

3. Which commands are necessary to configure a GRE tunnel? (choose all that apply)

4. Once you know the two endpoints of the tunnel, you need to add either a routing protocol or static routes so that traffic can be routed correctly.
