Hi Gang,
I have been presented with a project to configure a remote isdn connection.
We will be using ISDN to connect a remote site into our central site. I
have two separate ISDN lines at each end which I want to be able to combine
(multilink) for a total bandwidth of 256.
I believe this can be done using a rotary group but I have never configured
this before. I am used to configuring legacy ddr. So I have been looking
on the Cisco site and in documentation cd and there are a couple of
questions I have.
First, here is some basic information on my two routers. The central site
is composed of a Cisco 3640 with a bri card and internal NT1's. The remote
site will have a Cisco 2611 with a bri card and internal NT1's. I will be
connecting two bri's on each end. The remote end will be calling in to the
central site but no one on the central site will be calling out.
I have found the following information on the Cisco site regarding
configuring legacy ddr:
http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/12cgcr/dial_
c/dcbri.htm#21895
I have a couple of immediate questions. One is, do I need to identify the
SPID's and if so, where? Normally I would define these under the bri
interface. By the way, my switch type is basic-ni on both ends.
Also, under the interface dialer would I need to define a dialer map
statement for each separate channel? i.e.
dialer map ip 1.2.3.4 name centralsite broadcast 1112223333
dialer map ip 1.2.3.4 name centralsite broadcast 1112224444
dialer map ip 1.2.3.4 name centralsite broadcast 1112225555
dialer map ip 1.2.3.4 name centralsite broadcast 1112226666
Here is what I have as far as a config so far on my remote router:
interface BRI1/0
