Need some help understanding and resolving the issue

10.205.248.25 is dropping pings and when I checked the routes to the address from L3 switch and the router it keeps getting advertised by BGP and OSPF alternatively..What should I be doing?

Router#sh ip route 10.205.248.25

Looks like a classic case of recursive routing. Post the config of the device for which the /30 is being advertised.

The config is not the device that is sending the route...

So have a look @ 10.255.249.2 and you might find either an incorrect ACL or Prefix list that contains the /30 in the redistribution.
