(BSCI) Redistribution questions

1. With IGRP -> EIGRP, redistribution is automatic within the same AS#. Do the IGRPs show up as an internal or external EIGRP route?

2. I tried to set up a lab:

RouterA --- RouterB --- RouterC --- RouterD --- Router E

RouterA: ISIS L1
RouterB: ISIS L1-L2 + EIGRP
RouterC: EIGRP

I'm trying to redistribute ISIS L2 into EIGRP.
I configured summary-address on Router B.

RouterC should receive all the routing information, right?

I noticed my RouterA didn't have a default gateway setup; should it be automatic when there is only one L2 router?

    When you redistribute into EIGRP you need to set the metrics. If you do not specify metrics going into EIGRP it will use a seed value of 0 and the routes won't be entered into the routing table.

    You can set a static default route on RTR A or you can advertise one to it via RTR B. It will not automatically have a default route.

    Thanks for the reply.

    I had no problem redistributing into EIGRP, except with that one ISIS L2 example. When I did it with all L1-L2, there was no problem. I think it's just my misunderstanding of ISIS, so I will take another crack at it again.

    PS. Any reply to the first question. I don't think my 12.3 and 12.4 routers can do IGRP?

    Just my 2 cents...why do you care what IGRP does? No one uses that anymore including the tests :)
