Hello,
I have a question regarding the difference between commands.
For example, i setup a network with 3 areas.
(area 1)<->(area 0)<>(area 2)
Area 1 = nssa area with an abr going to area 0.
On area 1's abr i want to summarize the routes from the nssa area so that when it gets to area 2 they are condenced.
So i would think this would be the command layout.
root@area1-R4# show protocols ospf
area 0.0.0.1 {
nssa {
default-lsa {
default-metric 10;
metric-type 2;
type-7;
}
area-range 100.0.0.0/24;
}
But when i look at the abr bordering area 0 and area 2, and a router in area 2 i still only see all the smaller routes and not the summarized routes.
But, if i move the area-range command to be directly under area 0.0.0.1 forinstance
root@area1-R4# show protocols ospf
area 0.0.0.1 {
nssa {
default-lsa {
default-metric 10;
metric-type 2;
type-7;
}
}
area-range 100.0.0.0/24;
I see only the summarized route in the abr facing area 2 and all the routers in area 2 as well.
Is there something i am missing, Could anyone help explain the difference between these two commands?
set protocols ospf area 0.0.0.1 nssa area-range 100.0.0.0/24
and
set protocols ospf area 0.0.0.1 area-range 100.0.0.0/24
Thanks for any help.
