Hi,
We are going with a Cisco 2921 router with 2 VWIC2-2MuseFT-T1/E1 cards with three private T1 lines for the MPLS and 1 Public T1 for the internet.  What configuration do I need to do in the config to bind these 3 channels together?
The IP addresses are:
Corporate 192.168.0.0
Warehouse 1 192.168.1.0
Warehouse 2 192.168.2.0
Warehouse 3 192.168.3.0
Warehouse 4 192.168.4.0
Warehouse 5 192.168.5.0
All internet connectivity and servers are at the corporate location.  All warehouse locations have a private T1 and a Cisco 1921 router.
Thanks

A lot of your configuration depends on the mpls provider. Some use multilink ppp and some use multilink frame.

Who is the provider and which offering are you using? An example would be AT&T offers PNT, EVPN and AVPN as MPLS solutions.

Hi,
Sorry about the delay I was out of office.  The multilink is now done with PPP.  How do I know if MPLS is working?  I ran ip cef and is-is routing but I do not know if MPLS is active.  I can communicate between the two routers which is soon to be 5 routers.  1 cisco 2921 with 3 T1s into and 4 cisco 1921 with ethernet connection over 1 T1 with an adtran router from quest.
Thanks

if the 2 sites are working then your provider has mpls configured correctly.

Just saw that the IOS I have 15.0(1M) doen not have MPLS.  I need 15.1T to have it.  I can download 15.2.T3 to get it.  I guess they are working now because of IP Route statements.

Thanks

Sorry I missed your reply.

You don't have to support MPLS on your router only the connectivity to your provider such as t1/ds3. The provider will handle all MPLS configuration and traffic.

While it is possible to put two routes in place with the secondary having a higher metric, this may not always work. In the event of a failure that does not bring down the physical interface on the router the primary route is not removed. There is a…
