The word 'understands' tags is a bit misleading. The routing protocols do
not look at or use this tag they merely transfer the field from one to
another.
OSPF and EIGRP support 32-bit field but RIPv2 only has a 16-bit field.
Therefore remember to keep tags below 65535 if you are using RIP.

Subject: Re: Tagging routes
As per doyle's vol1 , only RIPv1 and IGRP do NOT understand tags .
so you can do this solution in the two directions like that
route-map ospf2eigrp deny 10
match tag 88
!
route-map ospf2eigrp permit 20
set tag 77
!
do the opposite for Eigrpp .
