In the following scenario madrid is ABR for OSPF 10 and also ASBR. viena
is
connected to OSPF 10, area 1, and to a RIP cloud and is in charge of RIP
redistribution into OSPF 10... The subnets 16.0.0.0 ->16.3.0.0 /16 are
injected into
OSPF by means of viena and appear on madrid's routing table with the tag
N1...
(no problem, till now...)
The point is : the command
router os 10
summary-address 16.0.0.0 255.0.0.0
has no effect on madrid... It receives the routes from viena but does
not inject
them into area 0... There is no entry for network 16.0.0.0 on london's
routing table.
By analyzing the attached configs and routing tables, can anyone tell
me what is
missing for succeding on this scenario?
Thanks and my best regards,
Alexandre
