Hello experts,
I have a testbed configuration with Nexus 7700 - F3 (NxOS 6.4 and latest 7.2, too) and try to configure a simple xconnect. The AC and MPLS interface are on the same F3 card.
Everything seems OK control-plane-wise but the PW doesn’t come up. The 7K is connected directly to an ASR1k. The configuration is done in a simple not-mixed VDC.
The question is - is this a supported topology (if so, what am I am missing in config)?
Thanks, kind regards,
Eduard
