- Having multiple networks has confused me. all 4 networks have been used by servers and devices in the datacenter.
I am in the process of congurin two routers 6506 for BGP with two providers but one is only ready now for turn up and the other will be in two weeks, so I will be multihomed.
these two routers will pass over a Layer 1 physical fiber link and connect to two other 6506s - full mesh.
I am planning to run EIGRP between these 4 routers and have three or 4 networks to advertise in BGP and EIGRP. I assume the same networks will be used in the EIGRP config as well.
One of the networks is a class C /24, from which I want use an /28 to use for for Interface connectivity between these 4 routers (Cisco 6506) but not having design an EIGRP network from ground up before I cannot tell the relation between these /28 that I want to use to connect these router together and the othet network blocks that I have - All Public IP blocks.
here is the block from which I want to use an /28 for router's connectivity in EIGRP :
Other network blocks that have been advertised in BGP to Provider.
216.x.x.x - 40 Class Cs
216.x.x.x - 16 class Cs
well, I guess my question is how do I assign IP addresses to those interfaces full mesh?
You see, all the examples that I have seen deals with two different networks between two routers running EIGRP or between 4 or more routers running EIGRP!? and this has confused me given the fact that I will be using IPs from one network to connect all these 4 routers to run EIGRP between them!?
Either, there is no issues at all and I am only confused not having this done from ground up before or I am making a big mistake?
this is for a web hosting compant and downstream (going from servers to these routers) are two 6509 swithces L2 only where I will have PVLANS on them while having the Primary VLAN Interface for these PVLANs on the next hop to these switches i.e. on two of the 6506s (routers) that are participating on the EIGRP. - though the last piece of information might be usefull to clarify my orginal question on EIGRP.

Please help so that I can understand this scenario.
