Hi,
now it is working. The default-route will be automaticly redistribute to
RIP on the NSSA ASBR.
The problem was that I used route-maps for redistributen. With the "set"
command
in the route-map I set the metric to 10. Example:
route-map OSPF-TO-RIP permit 10
match ip address prefix-list OSPF-TO-RIP (permitted prefixe)
set metric 10
This config didn't worked correctly. Then I set the metric (for
redistributed routes)
under the rip config with the "default-metric" command. After the change
my errors disappeared.
Working config:
router rip
redistribute ospf 1 route-map OSPF-TO-RIP
passive-interface Serial1
network 10.0.0.0
default-metric 5 <---- new !!!!
Thanks for everybody who helped me by solving this issue.
