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

[Nathan Brookfield]

VRF's with BGP running lower timers and you'll never look back, very reliable, fairly easy to implement even with your primary connection on PPPoE and the other on a routed VLAN.


Worse case you can just have your LNS act as a BRAS and still use PPPoE on your Layer 2 services.

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

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?
