How do i solve this problem?
I am sending a summary address of 0.0.0.0 on both interfaces on r3 and r4 to the grey stub sites. i am protecting to sending that summary back into eigrp 1 on the same routers by blocking it in a route-map when redistributing back as i dont want transit traffic to go through the stub sites.
That works fine. But what if another router in eigrp 10 decides to redistribute a static default route. Say r6. I can match on a interface, s1/0 on r3 and r4 for sure, and that works, allowing the default from r6 on to r5, but the summary's on r3 and r4 point to null causing mayhem/loop when i trace from r5 to the loopback on r6.
I remember there is a command (at least in OSPF, discard-route?) to not install the summary to null, but i am not sure it's wise to remove it?
Sorry you can't see R5 in this picture, it's to the right where R3 and R4 meet.
