[cisco-bba] PPPoE AC redundancy

[Denis V. Schapov]

Hi,

What is the best practise to get server side redundancy for >1 Cisco LNS routers acting as
PPPoE AC for clients on Ethernet, 802.1q ? Didn't found in rfc some priority TAG for PADO
packet to force clients using only one of PPPoE AC in normal scenario and switch over to
2-nd only in the case of 1-st AC failure. Or this can be and must be implemented on PPPoE
client side to choose first AC with specific AC-name/Service-name and in the case of
primary AC failure ask/choose for another Service-name/AC-name ?

Thanks.
