Hey, John -
This is really cool, because this is exactly the way I do it with distance.
However, someone (forgive me if I forget who), mentioned to just use a the
same tag....since that tag was added as it comes in to the area, it will not
get redistributed back to original network. I have been thinking about it for
awhile, it seems to work and is easy to work with. However, no one commented
on it. Any thought on this? Here it is....
router os 1
redis eigrp 100 sub route-map REDIST
route-map REDIST deny 10
match tag 100
route-map REDIST permit 20
set tag 100
router eig 100
redis os 1 metric 1 1 1 1 1 route-map REDIST

tags is a great method of controlling your redistribution of routes.
the
method i use is:
router os 1
redis eigrp 100 sub route-map e2o
route-map e2o deny 10
match tag 110
route-map e2o permit 20
set tag 90
router eig 100
redis os 1 metric 1 1 1 1 1 route-map o2e
route-map o2e deny 10
match tag 90
route-map o2e permit 20
set tag 110
i just use the AD of each protocol as my tag vaule.

issues need to tackle
1. routing loops
2. suboptimal routes.
i have seen different approch to resolve above two.
A. I use route-map with tags to solve 1 and distance with acl to solve
2.
B. some work books i have seen , where they use distance with acl to
reslove both 1 and 2.
in both cases A and B still needs an ACL or prefix list.
While reading the DoC CD in the morning i thought of a different
solution
without using ACL. I donot have a online lab to test this out at this
moment.
This is the solution i am thinking
C. use route-map with tag to solve 1. and use opsf distance command to
manipulate the external distance
ex: if we need to make the distance for external route to 171
ospf distance intra-area 110 inter-area 110 external 171
with this we donot have to use an ACL.
Thanks.
