>> Or is this something I can get from AT&T..
yes, just ask for an EoMPLS service that is L2VPN service over MPLS is the best choice to avoid performance issues.
I used L2TPv3 on C3725 or C3745, I don't know for 2821 try using feature navigator
I've checked basic L2tpv3
12.4(20)T ADVANCED ENTERPRISE SERVICES WITH SNA SWITCHING c2800nm-adventerprisek9_sna-mz.124-20.T.bin
this requires 256MB RAM and 64 MB flash
Hope to help
EoMPLS is a different service from L3 VPN so it requires to buy a new service from your provider with a different access link on each side. Price should be low but however it adds to current expenses.
Otherwise you can try with L2TPv3 on the CE routers, the question is how much traffic do you expect on this DR service ?
I'm afraid 2821 cannot handle high volume traffic over L2TPv3.

I also have a question for stretch VLAN. I have ptp between two sites and how can I strectch the vlan from one site to another site. BTW, I have cisco 2691 router.
if you have a Frame-Relay point-to-point link you can use bridging over the WAN.
Be aware that all broadcast traffic will be bridged and will consume bandwidth
bridge 1 protocol ieee
bridge 1 route ip
int ser0/0.100 point-to-point
frame-rel interface-dlci 100
ip address 10.2.3.1 255.255.255.252
ip address 10.10.20.1 255.255.255.0
desc l3 interface for Vlan over two sites
the same must be done on the other router
Hope to help
I have 2xT1 with multilink. Is that going to work the same configuration? This is my first time for this kind of task. Thanks in advance.
I strongly recommend against extending your broadcast domain over a 3Mbps unreliable WAN link. Some odd results can occur in your network.
I'm sure your requirement can be met in a routed network. I haven't seen a design that calls for extending Vlan over a slow WAN. Yes, I'm aware of some Microsoft products that require services to be in the same LAN but I'm sure there are ways to make it work over a routed network.
If this needs to be done, then I would use an l2tpv3 psuedowire on the routers at each end of your MPLS cloud.
We do this occationally in customer nets where they need effectively a l2 vlan spanned accross sites.
you'll want a dot1q int on each router with no local ip address and set up Xconnect over the IP MPLS cloud.
Am I able to do this with a new dot1q subinterface? I don't want to impact the existing routed traffic. I just want to add this subnet to this location without removing the other different existing subnets.
