Unfortunately, the lines are being resold by a CLEC. My understanding is the
PUC/PSC doesn't take complaints from CLECs and, since the customer is customer

VRRP is to HSRP what 802.1q is to ISL...
I highly recommend using VRRP instead of HSRP because:
1. It is a more robust protocol
2. It is vendor agnostic
3. Being vendor agnostic it is more likely to have a continuing future.
Does anyone still use ISL?
