I currently have a router using a single cblock from one of our providers. Our other provider just allocated us a new cblock. They are properly pointing the new cblock to us. I'd like to start using it...
Situation:
Provider A - CBlock1 (Currently Being Used)
Provider B - CBlock2 (Not Being used yet - but setup properly via ARIN and the provider)
We currently have a BGP session with both providers advertising CBlock1. I'm not sure this matters at this point... but just in case it does I'll mention it.
Four T1s - All 4 are funneled into our small network with Ethernet 0/0. The local router is the only way in/out of the LAN. I bound an IP from each CBlock to the Ethernet 0/0 interface using the IP from the new CBlock as a secondary IP.
What else do I need to do in order for the router to pass on a packet from the internet destined for the new CBlock in to the local network? I can ping the router's secondary IP address from a machine inside the network. If I trace to an IP on CBlock2 from somewhere else in the world, it DOES head to our router - but our router is not passing on the packet into the local LAN - it doesn't know what to do.
Do I need to add the other CBlock as a new network under "router rip"? Do I need to add the new network to my "router BGP"? (Note at this point I just want to get the block working - I'm not worried about BGP unless I have to).
Thanks in advance...
