Cisco 7204VXR - IPFR to AVPN circuit

[zzbronski]

Guys,

Will the exisitng  PA-MC-2T1 module work for this WAN circuit upgrade? They are currently configured for a IPFR circuit with two T1's. New circuit has been installed but we need to confirm the existing card will support the new AVPN circuit. Hardware in chassis listed below.

From your question, it appears you are describing the type of service that runs over the link itself (IPFR = Internet Protocol Enabled Frame Relay) or AVPN (ATT Virtual Private Network).

Is the VPN going to be delivered over frame relay ?

Are you changing bandwidth ?

[zzbronski]

No, the circuit is changing from ip frame to ppp. I just need to know if the module currently used, PA-MC-2T1, will work with the new AVPN circuit for ppp encapsulation as opposed to IPFR. I have not been able to find anything in Cisco about it. When I looked up the module in Cisco it says it can be used for voice PRI's. But this is for WAN circuit.

The bandwidth is not really changing, is still one T1. But due to the nature of the different type of circuit, IPFR to AVPN, the bandwidth is changing somewhat because of the difference in overhead.

[vmiller · Accepted solution]

It should. Its just the encapsulation method. if one one of the T-1's on the NM is not used right now go into config mode for that int, and try encapsulation ppp

I figured it out. I had to assign a channel-group to the controller in order for it to show the other serial port. Thanks for kick starting my brain!
