Re: tunnel point to point vs physical point to point

Hello,

jasonsig a écrit :
If you have 2 systems on a point to point link you would address them
by a /30 block?

No, this would be a waste of address space.

When creating 'gre' tunnel you can use /32 for example
ip addr add 1.0.0.1 peer 1.0.0.2 dev mydev.

Correct. The local and remote addresses do not even have to be next to each other.

why can't /32 of arbitray addressing be used on a point to point
between 2 systems?

It can.
