I'm trying to set up a VPN for a few sites and I'm testing how to get traffic from an ATM cloud through our switched network as seen below. In theory, it should be Layer 2 all the way from the CPE to the Test Machine.
Test Machine on VLAN 903 (22.214.171.124) -> [Switched Network] -> Core Router with ATM and Ethernet sub-interface configured on it -> [Third Party's ATM cloud] -> CPE (192.168.14.2)
I don't know if I'm doing something wrong or not but I CAN'T ping from the test machine to the CPE and vice versa.
Core Router config:
bridge 2 protocol ieee
bridge 2 route ip
interface ATM1/0.304470 point-to-point
description ATM VC
atm route-bridged ip
encapsulation dot1Q 903
ip flow ingress
Is a BVI interface required?
I can confirm that the Layer 2 between the ATM sub interface and CPE is working. I put an IP address on each end and was able to ping end to end.
I can also confirm that the Layer 2 between the Test Machine to Interface Gig0/0.903 is working. Similarly, I put an IP address on each end and was able to ping end to end.
So my questoin is - can ATM and Ethenet co-exist by putting them both into the same bridge group as seen in the config above such that the CPE which is connected to the ATM cloud is able to reach the test machine which is attached to the ethernet sub-interface on vlan 903 through the use of this bridge group?
If this is not possible, are there alternatives to what I want to do?
What kind of VPN you are trying to build here? I see you are trying to internetwork ATM and Ethernet and build some L2 connectivity... In fact it's rather design question and I need to understand your requirements in order to pick a right technology. If you can give some more background information on what exactly you want to build we can discuss options and benefits L3 vs L3 connectivity between the sites.
How big is the network, how many sites, how big the sites are, do you want full mesh or hub and spoke etc...you got the ides. Without that it's hard to recommend anything....
Basically I was just testing layer 2 connectivity from a customer connected to a ATM cloud across, where by we put their ATM traffic onto a VLAN and carry it across our switch network to our data centre. I just wanted to make the connection from Site A to the Data Centre like a long piece of ethernet cable in a sense and carry layer 2 traffic back and forth between the two end points.
Data Centre -> Switch NW -> core router -> ATM cloud -> Site A
The simple solution was to put the ATM sub interface and VLAN into a bridge group on the core router. Tested this and it works good.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
