I am working on a new pppoe setup and am hoping to configure HSRP/VRRP or something else to eliminate to possibility of hardware failure. Running on a 7206vxr box with the following (pertinent) configuration:
ip address 192.168.41.1 255.255.255.255
ip mtu 1492
ip unnumbered loopback 41
no ip route-cache cef
no ip route-cache
no logging event link-status
no peer default ip address
ppp authenication pap
bba-group pppoe global
sessions per-mac limit 2
encapsulation dot1q 4
pppoe enable group global
Currently works. But if this interface or router dies, then so do the customers. Is it possible to set up a second 7206 box and run HSRP/VRRP on the virtual interface so if primary box fails, the secondary takes over?
I don't think you can because this is PPPoE: point-to-point logical link between your broadband NAS and the user.
Here, you should need a virtual multi chassis multilink PPP over ethernet
However the user can use multiple PPPoE clients: one pointing to NAS1 and one pointing to NAS2: the problem then becomes how to forward frames for/from the two NAS: this would require more info about your scenario
