I'm looking into setting up a backup interface for a remote site I have
the current configuration is a 1941 (15.1(4)M3) with two interfaces, lan and wan
I now need to create a failover path in case the wan link fails
I'm considering using a VSDL ISP who will provide me with an Ethernet port on a modem and then use PPPoE to authenticate to the ISP and get an ip address etc
I intend to use an IP SLA to create the failover condition and route traffic out the dialer interface if the primary wan link fails
traffic over both links will also be encrypted over a l2l tunnel using IPsec profiles
I've already set it up and tested in VIRL using standard Ethernet ports but haven't tested it yet with a dialer ip and PPPoE
I know what I'm looking to do isn't new but I'm hoping anyone out there can point me to a recent config guide or share their issues with a similar setup
thanks to anyone taking the time to read this or reply
