Prior to my question, I want to
ask you to forgive me. I'm a newbie, when it comes to Cisco
networking. So if my question is simple, I do apologize. I was thrust
into this position, as an emergency. They are not looking to hire
anyone else, so it's only me, for now.
We
have an ISP that has placed a Cienna switch, in our Datacenter for
internet service. This switch goes to our ASR 1000, and then to our
ASA 5540 firewalls. We just leased a new building, which is down the
road from our building. In order to connect them back to our
datacenter, our ISP said that they could do a point to point link.
They would place another Cienna router, in the new building, and
connect it back to our Cienna switch, in the datacenter. Our Cisco
infrastructure is as follows. We have a Nexus 7000 core, with 3750's
as our access switches. I purchased a 3750, for this new building.
I'm going to take the handoff, from the ISP, and connect it to the 3750
switch. Our building is strictly doing layer 3 routing with EIGRP. I
figure that if I can copy a running-config, from a similar switch, and
edit just a few items (such as the IP address, loopback address, etc),
I'll be able to continue the L3 routing back to our datacenter. Since
the datacenter Cienna goes through the ASA's, I'm assuming i'll have to
create a rule that would allow the new building subnet to pass all IP
through. Can anyone tell me if I'm going down the right path? I have
searched quite a few sites, but haven't received any hits. Your time
would be much appreciated. Thank you!
Hi Don,
It can be done but make a note that you are not doing on internet facing router,just connect the point to point link on the intranet router where you other sites used to connect to data center for accessing application.
Just configure the new building subnet in Data center for routing and allow rule for new subnet.
Hope to Help !!
