Hi i am having an issue where my R4 router can send a packet to R1 but then R1 just drops it, R1's routing table does not contain the IP for R4, but R2 and R3 do ? R1 caan not ping R4 but can ping the rest, i am ost :(.
I am trying to learn EIGRP and OSPF, i made some mistakes with my routes so i have them as defaults for now to try and find why this is not working.
I am using packet tracer, as i can't afford G3, i have attached my running configs below, can you help me solve why R1 and R4 won't ping each other please, honestly i have been stuck for weeks and i am getting behind, this CCNP is hard :(.
Here's the configs;
hostname R1
!
username ADMIN password cisco123
!
aaa new-model
!
aaa authentication login default local enable
aaa authentication login vty local
