Re: Dot1q problems ( Mac in Mac tunneling )

Hi Wim,

Currently I don't see 802.1AH (Carrier Ethernet) on the 'wire-closet'
switches. I don't know, but it could be supported on the 3750 Metro,
but I don't know that for sure.

As you call the same MAC address on the 2 sides is the biggest issue
with Q-in-Q (for example HSRP or VRRP have this issue). I know Nortel
has some intelligent stuff on 802.1AH actually :-)
