Hi,all:
If I redistribute between a classful and a classless routing protocol,
for example, RIP V1 and EIGRP, what will happen if I have some
discontiguous subnets in both routing domain? Will auto-summarization
still occur in the classful network boundaries? Let's say the boundary
router is running both RIP v1 and EIGRP with auto summarization enabled,
mutual redistribution is configured on this router, if I have a
80.160.1.0/24 subnet in RIP v1 domain, I also got 80.80.2.0/24,
80.80.1.0/24 and 80.80.3.0/24 subnets in the EIGRP domain, will the RIP
domain see these three /24 subnets from EIGRP domain or it will only see
a summarized 80.0.0.0/8 or maybe it will see nothing from EIGRP. I think
I already knew the answer here, which is RIP will see nothing from
EIGRP, but I could not explain this result? Why RIP could not see the
subnets? What if I am running RIP v1 and OSPF? Will that make any
difference?
Please help clarify!
Thanks a lot!
