AOS: route with ebgp vs. ospf but ospf wins?
Please advise why it happened this way
=>169.1.11.0/24 is the ebgp route
=>169.1.11.0/24 is the ospf route
But EBGP admin distance is 20 while OSPF admin distance is 110 so EBGP route should be preferred and active right?
Why below showed that it’s active on OSPF?
Regards,
C.
