Lc-atm

I am unable to get an LC-ATM interface to work on my 7200 in my lab. Ive attached a picture of my lab to this post:

The edge atm router is SanDiego and Raleigh. The LSR is Denver.

Configs for SanDiego:

interface ATM1/0
no ip address
no atm auto-configuration
no atm ilmi-keepalive
no atm address-registration
!
interface ATM1/0.101 mpls
ip address 192.168.12.1 255.255.255.252
pvc 0/101

Configs for Denver:

interface ATM2/0
no ip address
no atm auto-configuration
no atm ilmi-keepalive
no atm address-registration
!
interface ATM1/0.100 mpls
ip address 192.168.12.2 255.255.255.252
pvc 0/100

I am at work right now, but if you have any config advice, please let me know until I can get some MPLS show commands and/or debug output.

What IOS Version? Support for LC-ATM was removed in 12.4(20)T

Is this real equipment or dynamips?

Yeah, that will do it:


BOOTLDR: 7200 Software (C7200-ADVIPSERVICESK9-M), Version 12.4(2)T, RELEASE SOFT WARE (fc1)



an i am using dynamips, which I will say, has been extremely helpful. I have been able to do any lab for my 642-611 thus far; well, with the exception of lc-atm.

Correct me if I'm wrong but in this situation couldn't you use AToM for ATMoverMPLS?

xconnect on the ATM switch interfaces to allow for a L2VPN over the MPLS core?

I kind of wanted to stay on track with the book, besides, I dont know how to do that

the legacy command that implemented the same L2VPN for ATOM was previously

mpls l2transport {etc}

which they conveniently changed to

xconnect {etc}

My knowledge of MPLS is only limited at the moment and I've only seen it in effect at the new company I currently work at. But this is how we used EoMPLS(Ethernet over MPLS) to extend an IPTV VLAN over a L2VPN from one side of the country to the other across our MPLS core.

Hmmz.... however now that I look at the compatible transports I don't see ATM to ATM...... Only ATM to Ethernet, ATM to Frame-Relay.
