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.
