RE: OSPF AS process ID

Hi,

AFAIK, there is no AS number for RIP, neither there is a Router ID for RIP.
The Process ID in OSPF is local to the router, but affects the interfaces
that are running in that box, hence you will need to redistribute between
processes, if you are learning LSA from Neighbors, or generate a default
route, to that Process ID Neigh Adjacencies.
EIGRP Router-ID is used to control External Information, useful to avoid
routing Loops.- And off course that the EIGRP AS# must be the same between
neighbors to make them neighbor, there are other important parameters in
EIGRP like K(1-5), that must be the same between neigh.

Just my 2cents
Victor.-

That is correct. With OSPF you are specifying the "process ID" which is an
internal parameter to that router. In contrast, when entering router rip
<AS #> or router EIGRP <AS#> you are specifying the autonomous system that
the router will participate and accept updates for.

Hi,

I read in couple of article, the OSPF process ID on two or more connected
router not necessary to be the same.

e.g one router is running ospf process id 1 and other 100 ??

router ospf 1
network 0.0.0.0

and

router ospf 100
network 0.0.0.0

With RIP and eigrp/igrp the process ID must be the same.

Thanks
