[c-nsp] ipv6 cmts (uBR7246VXR) and arris cable modem TM602G

[Aaron]

Y'all know if this works ?  Trying to get ipv6 (6vpe) working on cisco cmts
(uBR7246VXR) and arris cable modem TM602G

 

I have this in my lab currently.  I see nd and icmpv6 and various traffic on
debug output of cmts as being sent out bundle 1 interface. but I don't see
it arrive on the computer hanging off of the ARRIS TM602G cable modem.

 

In the opposite direction, I see the computer (cpe) send neighbor
discoveries, and dhcpv6 solicits, but I don't seem to be getting that
traffic up at the cmts.

 

 

V6 works from cmts to internet. just not across rf domain towards modem and
cpe.

 

..from cmts----->to internet
