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?
