Dear All,
I have L2VPN between two PEs and I am using LT interfaces on logical
systems. Looks like the control plain operations are working
correctly,however, the forwarding plain doesn't seem to work. It could be
a bug or limitation of the LT interfaces. I will be glad if you can verify
that for me.
CE1 interface facing PE1 is configured with 10.0.10.1 and CE2 interface
facing PE2 is confgured with 10.0.10.5.
Thank you in advance.
(topology)
CE1 - PE1 -- PE2 - CE2
NO* ARP* on the CE's.
