I reproduced that scenario from the book:
R1 R3 OSPF domain
\ /
R6
|
R2
|
R4 <------------- mutual redistribution
/ \
R5-R7 EIGRP domain
I tried to do different things but I can't get EIGRP routes to be injected
back to EIGRP from OSPF. EIGRP summary: 182.18.0.0/16, OSPF summary:
172.16.0.0/16.
How do I observe that summaries are being redistributed from EIGRP to
OSPF and "bad routes" - back to EIGRP ? I can't justify filtering out OSPF
summary when it redistributes EIGRP.
Please help !
