At what point during redistribution is a route-map processed? In other
words, if I want to redistribute from EIGRP (supports tags) to IGRP (doesn't
support tags) can I match tags in the route map and then let those routes go
into IGRP?

Route maps are essentially built around an "if then else(if)" logic. the
point of their activation is the point of their inception.
therefore if you were to have a route-map such as:
route-map eigrp_tag_igrp permit 10
match tag X
set metric 1 100 255 1 1500
and the redistribute statement:
Thanks Chuck. This is actually part of a greater redistribution plan to
match routes already in EIGRP from another protocol and prevent them from
going into IGRP. I then permit those routers in the other protocol into
IGRP and deny the EIGRP routes in that protocol. Since I can use the tag to

I did a little bit of research on this, being curious as to the reason for
your question.
essentially, the logic illustrated below works just fine. the questions that
came up are:
1) how to tag the eigrp routes in the first place and
2) why the routes may not appear in IGRP assuming the eigrp ta
On 1 router I am redistributing OSPF into IGRP, EIGRP into IGRP, and OSPF
into EIGRP. Downstream, I am redistributing OSPF into EIGRP. The loop in
this scenario is deadly so I need to find a way to let both EIGRP and OSPF
redistribute only routes originating from their domains into IGRP. The pl
hmmm interesting discussion. the scenario reminds me of something I saw
from someplace called NT Labs, maybe?
Let's see if I can sketch the scene:
R1-R2-R3
IGRP bunch of stuff OSPF/EIGRP
R2:
router IGRP
redistribute OSPF route-map filter-
This is actually something a co-worker has drawn up for me. One of my
weaker points has always been multiple redistribution between multiple
protocols. Goes something like this:
R1-R2R3

ooh ooh, I'm getting ready to have some fun with this one. got it mocked up
in my lab. just want to clarify something prior to jumping through hoops and
writing a report.
On R4 you have mutual redistribution between OSPF and EIGRP? ospf---> eigrp
and eigrp -ospf ??
On R2 you have the same -
