hi,
when I'm trying to manipulate the routing decision using as-path prepend, 1
(r8) of the 2 routers in the same AS reflect correctly the route preferred,
while the following one (r7) have strange result, which he won't prefer the
shortest as-path ???
am I doing the correct things ?
any clues ?
r7# sh ip bgp
