RE: Route redistribution

Sorry. I made the assumption you were going for going for SP, I just saw you're security, so my bad there. Anyhow, R6 is going from RIP to EIGRP, right? The SG writer doesn't care that it's external EIGRP, they are just showing how to identify the route. You can pick any value you like. The concept being tested is the use of tagging to allow for future additions of routes with dynamic loop prevention. You'll get the same results if set the tags to 1. Some people like to see where the route originated from or where it was redistributed at, if you're told to use a certain tag, then obviously you should use it. Otherwise, use something that makes sense to you.

Hmm. This is for RS, but switch 2 they have defined as 8. So EIGRP on
sw2 would be 890.

Ok, so I agree workbook uses this value of 890 ( sw 2 = 8 and EIGRP = 90
) but is CISCO expecting same thing in the actual lab?

Marcin,

Just going out on a limb here, but are you working on R3 and R8 (this is
for SP?)? It's typical of the IE workbooks to use router number and
administrative distance of route in the tagging. The values are used
for your IGP to make decisions upon later. Only one tag per route,
usually set to nothing unless it has come from BGP.

Here is the solution from IE workbook when redistributing between EIGRP
and OSPF.

I am confused with "match tag" I know you can tag the routes and stuff
but what is 890 or 390. Where these values came from? How can I look
these up?

Is this a correct solution ? can some one shine some light on that.

thnks

router eigrp 100
redistribute ospf 1 metric 10000 1000 1 255 1500 route-map OSPF->EIGRP
!
router ospf 1
redistribute eigrp 100 subnets tag 390
!
route-map OSPF->EIGRP deny 10
match tag 890
!
route-map OSPF->EIGRP permit 20
