Im confused about something, maybe someone can help.
I am on a router that is running OSPF and BGP.
It natively advertises a network using the "network" command under its BGP process.
But I am getting a strange output from the "sh ip bgp <prefix>" command. What is strange about it is that it shows a next hop of 10.36.125.249 but that is our firewall and it does not run BGP. Also, it selects OSPF as the route to place in its routing table when this router itself originated the route!
Can you say 'confused'?
