after reading the junos rip implementation,I have several problem about rip
configuration in junos; the following example came from RIP configuration
guidline in junos routing document.
----------------------
[edit policy-options]
policy-statement redist-direct {
from protocol direct;
then accept;
}
[edit protocols rip]
metric-in 3;
receive both;
group wan {
metric-out 2;
export redist-direct;
neighbor so-0/0/0.0;
neighbor at-1/1/0.0;
neighbor at-1/1/0.42;
neighbor at-1/1/1.42 {
receive version-2;
}
}
group local {
neighbor ge-2/3/0.0 {
metric-in 1;
send broadcast;
}
}
------------------------
First question: Do the above router will advertise routes learn from
"neighbor so-0/0/0.0" to "neighbor at-1/1/0.0" with metric 2,regardless of
what metric the routes have? in other words,in same group, when metric-out
is configuated,the routes learned from neighbors in the same group will be
advertised to neighbors in same group using metric-out? or metric-out only
apply to routes being advertised learn from other group,and it do not apply
routes learned from neighbors in same group.
the second: in group local in above example, because of no export policies
in group local configuration, will the router have any routes advertised to
neighbor ge-2/3/0.0? if it is right, the send broadcast statement is no
useless?
the third :In rip configuration in Junos,the export policy for export routes
from protocol direct is necessary,otherwise,the directly networks are not
advertised to neighbors,regardless of the interface being included in
neighbor. unlike rip, ospf will export the directly route as long as the
corresponding interface name is include [protocol ospf area number].
thanks in advance
Regards
