Heres the setup: R1(Gi0/0) > Management server. Simple question. Interface Gi0/0 on R1 has IP 10.254.254.110 and Management Server has IP address 10.254.254.253 (This is in a /24 subnet). The router can ping the management server and vice versa. So heres my question. On R1, under interface gi0/0, there is the config listed below: (config)# interface gi0/0 (config-if)# ip access-group 101 in (config-if)# ip access-group 99 out (config)#ip access-list 101 permit ip 10.254.254.0 0.0.0.255 10.254.254.0 0.0.0.255 (config)#ip access-list 99 deny any any So my question is, the inbound ACL allows the management server to talk to the Router, but shouldn't the return traffic from the Router back to the Management server be blocked due to the 99 ACL? Or does the Router do a pseudo-stateful type thing where the follow-on traffic is allowed after it is matched by an inbound ACL? Maybe I am just overthinking this but it would be very helpful if someone could explain. Thank you ahead pf time.

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?
