Hi John,
The second method is good(deny/match tag and then permit/set tag). But remember, even though these statements stops looping still on the mutually redistributed router(both) install higer AD routes as lower AD routes(RIP routes as OSPF routes)(Example: between rip and ospf, redistributed router install rip routes as ospf routes becase of admin distance, so create a access list to include all rip routes and under rip router configuration mode add a distance for those routes less than ospf(say 105). Hope this helps

hi folks,
i'm practicing redistributing between 2 protocols with 2 points of mutual
redistribution. i have found to different route maps that i'm told accomplish
the same task but i'm not really sure which is the best method and why....so
here they are
r1--------------ospf/eigrp----------------r3
- r2 -
- -
- -
r4--------------ospf/eigrp-----------------r6
r5
r2 and r5 are performing the redistribution.
method 1:
R2
Router os 1
Redistribute eig 100 sub route-m e2o
Router eig 100
Redis os 1 metric 1000 100 255 1 1500 route-m o2e
Route-m e2o deny 10
Set tag 4110
Route-m e2o permit 20
Route-m o2e deny 10
Set tag 490
Route-m o2e permit 20
R5
Router os 1
Redistribute eig 100 sub route-m e2o
Router eig 100
Redistribute os 1 metric 1000 100 255 1 1500 route-m o2e
Route-m e2o permit 10
Set tag 490
Route-m o2e permit 10
Set tag 4110
METHOD 2:
both R2 and R5:
route-map e2o deny 10
match tag 110
route-map e20 perm 20
set tag 90
route-map o2e deny 10
match tag 90
route-map o2e perm 20
set tag 110
router os 1
red ei 100 sub route-map e2o metric-ty 1
router ei 100
red os 1 in ex metric 1500 1 255 1 1500 route-map o2e
are both methods correct? is one a better practice than the other?
