Hi,
I have really grown attached to tags to help prevent
routing loops. This is an example of one I used to
redistribute OSPF into EIGRP:
route-map o2e deny 10
match tag 90
route-map o2e permit 20
match tag 120 110
!
route-map o2e permit 30
set tag 110
So, I use the admin distance to help me remember what
the tags means. First, I denied EIGRP from EIGRP. Then
allowed anything from RIP or OSPF. If I had not set
the tag, I assumed it was from OSPF and used the tag
110. This can save lots of time instead of using
distribute list...
