When a static route is removed from the IP routing table, it is still being redistributed.

So here is the situation I am facing in a packet tracer topology: I have a Router (R1) that has one interface configured for a point-to-point network and the other interface is in an EIGRP broadcast network. I have created a default static route pointing to the neighbor IP on the distant side of the point-to-point network and redistributed it into EIGRP. I see the default route static route in the EIGRP routers as an external default route and everything looks good. The problem comes in when I shutdown the point-to-point interface on R1 (thus the static route is removed from R1's routing table). Even when this default static route is removed from R1's routing table, all the internal EIGRP routers are still seeing this default static route as external and being advertised by R1. I have cleared routing tables, topology tables, etc and they are still showing this route. Is this just a bug in packet tracer or is this how static route redistribution is supposed to work? Does redistribution match static routes sorta like it does for EIGRP connected routes (Ie. it looks to see what interfaces EIGRP is enabled on and advertises then out even though they are seen as connected in the routing table)? Does it look at any interfaces that might match a static route and advertise them regardless if they are in the routing table or not?

When you shut down the point-to-point link, and there is no other way for r1 to learn the distributed default route from the other router then the default route coming via that interface should be removed from the routing table. Maybe this is a bug in the software you are running.

Hi @Whiplash2013 ,

 

On occasion, PacketTracer does not behave as it should.

I suggest save your exercise and close/open it.

This often solves the problems of the behavior of the program.
