[AusNOG] High availability options for terminating point-to-point Ethernet (on Cisco CE)

[Matt Selbst]

Hi,

Hoping for some advice. What is everyone doing for
terminating point-to-point Ethernet services like AAPT's e-Line in a high
availability environment? Cisco environment.

With PPPoE, high availability was much easier as you could just have
multiple LNS's and failover easily when the client would re-auth. With
terminating a VLAN handoff on a /30 or /31 it makes HA much harder. If the
customer edge router dies, failover seems pretty hard. VRRP doesn't seem to
be an option especially with hundreds of customer sub-interfaces.

Any ideas?
