I am tring  to inject a default route in rip & eigrp without redistrubtion.
two of my routers R3 & R4 must use the default route.


I am succesfull when using a conditon route ( ie: acl+route map -only when network 1.0.0.0 is in R2 route table


but when I try  a eigrp summary + .default-information originate without the condition, it doesnt work


If possible can you tell me what I am missing or doing wrong.

Hello Pdriver,


the behaviour you see should be correct: RIP cannot generate a default route only because a default route is received in another routing protocol (EIGRP)


when you check for presence of EIGRP prefix  1/8  in IP routing table, RIP generates a default route.


otherwise you would need a static default route in IP routing table
