Figured this out.. I'll explain it here in case someone else runs into this
in the future..
By default cisco uses the same MAC address for every VLAN configured on a
6500.
The downstream switches were getting confused by this (customer was
combining the two vlans together rather than keepin
Yes, mac is per-vlan, but that's not a problem because the mac lookup
happens within that vlan. For example, on the 6k all SVIs share a mac, but
that's okay because each interface is the only MAC in that vlan (unless you
are using a physical loopback to a VRF, then you need to manually set the
MAC
A bit stumped by this one, perhaps someone has seen this behavior:
A particular MAC address is seen in two different VLANS: (Should be ok, MAC
address table is by VLAN right)
