Hi
I have cisco 7200 router and mikrotik and I configure ip routing ospf between them. I use these command to advertise default route to mikrotik
default-information originate metric 50
but my mikrotik show this route in its routing table with metric 20:
0 ADo dst-address=0.0.0.0/0 gateway=192.168.108.1 gateway-status=192.168.108.1 reachable via ether1-UpLink-Main distance=110 scope=20 target-scope=10 ospf-metric=20 ospf-type=external-type-2
With default ospf advertise route with external type 2 that neighbor router don't change metric. but in these case mikrotik change metric from 50 to 20.
