Hi
You will likely need to register your address space in the ARIN IRR. Some,
but not all, providers create/use IRR to create their routing filters. For
example a few months ago I setup peering with QWest and Level3 using address
space from both providers. The QWest space went thru the world's BGP tables
without anything being in an IRR, but the Level3 space was blocked. Once I
added the Level3 space in their IRR everything was good. I could have added
it to the ARIN IRR too, as the Level3 IRR is linked to ARIN's IRR.
To keep the number of posts/emails to a minimum I will also address your
question on memory size on your 2621...
You can do a little research on the CCO for an exact number for the size of
a route entry. But the bottom line is that you will not be able to take full
routes... back in Jan 01 the full table was almost 128MB it might be more
than 128MB by now. You might be able to take customer routes depending on
how big your providers are. I have heard rumors that Genuity and UUNet
together are more than 64MB. Also keep in mind that your router needs some
memory to run the IOS and the routing processes. If you are also doing ACLs
or queues there goes more memory. And if you run out of memory you are out
of luck! I would also keep a close eye on the CPU usage, the 2600 does not
have the most powerful CPU. So if you are running BGP, NAT, QoS, ACLs etc
and have _lots_ of traffic you could pass that magic 70% CPU level at which
a Cisco device will start dropping packets.
