I am interested in this as well. If you find something out, please let me know.
I currently have one border router that I would like to use VRRP to provide redundancy at the core. I have 2 QoS machines that are transparent bridges that I use STP since it is layer 2, if one fails, the switch enables the hot-spare and there may be a 30 second outage for the convergence. That is for layer 2...

But what I would really like to be able to do is duplicate my MT routers against equipment failure rather than network failure. Example: CPE ---- AP ---+------MT1----- + ----- WORLD | | +------MT2 ----- + MT1 and MT2 are both routing between AP and the world. AP is 172.16.2.0/24 WORLD is 10.0.0.0/24 MT1 has Internal (AP) address of 172.16.2.1 External (WORLD) address of 10.0.0.1 vrrp1 (AP) address of 172.16.2.254 vrrp2 (WORLD) address of 10.0.0.254 MT2 has: Internal (AP) address of 172.16.2.2 External (WORLD) address of 10.0.0.2 vrrp1 (AP) address of 172.16.2.254 vrrp2 (WORLD) address of 10.0.0.254 172.16.2.0/24 is routed to 10.0.0.254 172.16.2.0 side has a default gateway of 172.16.2.254 When the AP side of MT1 is unplugged MT2 takes over and only a couple of pings are dropped. However if the WORLD side of MT1 is unplugged about 4 pings time out and then I start getting destination unreachable. The VRRP failover works on both sides. If the WORLD side of MT1 is unplugged I can ping 10.0.0.254 and get a response from MT2. But on the internal end of things MT1 is still 172.16.2.254 so I get the host unreachable message. So what I'm really looking for is high availability for the router and I was hoping that VRRP would do the trick. I thought about bridging but at NOC I have several networks that all connect to my main MT router and I really don't want to bridge the traffic. If anyone has a clue, or can definitively say it can't be done with VRRP I would greatly appreciate the help. -- Sam Tetherow Sandhills Wireless ------------------------------------------------------------------------ -------- WISPA Wants You!
