All routes sent to L1 peers have an extra bit "enabled" (set to 1) which is
the ATT bit indicating that it has a route out of the known world.

Hi,

I am not sure what this means:

"A Level 1/Level 2 router that is not attached to another area can also
detect that a Level 2-only neighbor is attached to another area and set the
"attached bit" on behalf of this Level 2-only neighbor."

Would somebody please kindly expain what it means?

Thanks a lot!

Huang-Leng, Chang
