Group,
I have the folllowing scenario.
RIP (223.1.1.x subnets)
|
|
R5--------R4------------- R10
|<area0> | <---NSSA---->
|
R9
R5/R4/R9 are in Area 0.
R4 is ASBR/ABR (same as one of Doyles case studies.
R4 and R10 in NSSA area.
Configs of R4 are as follows:
r4#show runn
Building configuration...
router ospf 100
summary-address 223.1.1.0 255.255.255.0 not-advertise
redistribute rip metric 30 subnets
network 10.0.0.0 0.255.255.255 area 0
network 193.1.1.0 0.0.0.255 area 2
Question: Has anyone used the not-advertise option(Ver
12.1 code).As i understand the option prevents
advertising summary address when it does Type 7
translation.
But here for network 223.1.1.x subnets i feel there IS
NO TRANSLATION NEEDED TO SEND IT TO R9/R5. i dont see
the routes on R9/R5.
I know the translation will take place on R4 for NSSA
area for R10.What am i doing wrong ? or am i
understanding it wrong ?
The database on R4 is as follows:
r4#show ip ospf database
