Topology:
|--------R2--------|
| |
R1 R3
| |
|--------R4--------|
OSPF among R1, R2, R3.
EIGRP among R1, R3, R4.
There are two loopback 1.1.1.0/24,2.2.2.0/24 on R4.
They are redistributed into eigrp.
Mutual redistribute between OSPF and EIGRP on R1 and
R3.
Requirement:
R2 preferred R2 to 1.1.1.0/24, and R3 to 2.2.2.0/24.
Solution:
1) set tag 1 and 2 for 1.1.1.0/24 and 2.2.2.0/24 when
redistributed into eigrp.
2) Set metric 1 for tag 1 and metric 2 for tag 2 on R1
and Set metric 2 for tag 1 and metric 1 for tag 2 on
R3 when redistribute from eigrp to OSPF.
After I did this, R2 prefer one of R1 and R3 to get
both 1.1.1.0/24 and 2.2.2.0/24. And Sometimes R1
prefer OSPF for both routes, and sometimes R3 prefer
OSPF for both routes. It's because EIGRP external has
larger AD than OSPF.
R2 only see these routes in ospf database from one of
R1 and R3, not both of them.
What else I need to do?
Thanks.
