Hi, all,
Section 6.1 of 'OSPF DESIGN GUIDE'(http://www.cisco.com/warp/public/104/2.html)
mentioned that 'Simple password authentication allows a password(key) to be
configured PER AREA. Routers in the same area that want to participate in the
routing domain will have to be configured with the SAME KEY'.This means if you
want to use authentication under OSPF, then all the routers in the same area
must be configured with authentication, and must use the same password.
But in Terry's book 'Advanced IP Routing in Cisco Networks' page 185, there is
an example showing that all three routers in the same area were configured with
authentication using Type 1, but only two neighbors using the same password, as
we can say R1 and R2 using password 'xxxx', R1 and R3 using password 'yyyy'.
What's the point ?
Thanks,
Jack
