Dear Friends,

1) I have seen in several labs the following Wording (
the last one in Solie Lab, Bad and Ugly ):

"On R4, assign and advertise the loopback network
200.128.1.0/24 trough BGP"

The implementation in BGP is the network command, but:

I have to allow that all routers will be capable of
ping this loopback through IGP ?

2) When I am connecting a virtual link on order to
allow propagate a loop/new area, and area 0 has
authentication active, I know that I have to do "area
o authentication in the remote transit, but I have
seen a comment in IPexpert labs that says that we have
to activate authentication in the transit area to

Thanks for you help.

Ivan
