HSRP with a virtual interface ????

todd.adamson · ‎10-31-2008

Hello all,

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:

pdn enable

loopback 41

ip address 192.168.41.1 255.255.255.255

interface virtual-template41

ip mtu 1492

ip unnumbered loopback 41

no ip route-cache cef

no ip route-cache

no logging event link-status

load-interval 30

no peer default ip address

ppp authenication pap

bba-group pppoe global

virtual-template 41

sessions per-mac limit 2

interface g0/2.2

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?

Suggestions....Comments...

Thanks

Todd

Hello Todd,

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

Hope to help

Hi There,

HSRP only binds with a physical address.
