I recently started working in a place where the network was a mess and I want to make some changes for a best performance and management. We have 2 800 series running ADSL where I want to configure VPN tunnels (GRE) pointing to our remote site. I want to add local Internet and VPN failover making 2 groups, but I was examining the IOS and It doesn't support HSRP. As It doesn't support it I decided to check with VRRP, but the trouble that I have now is that the IOS doesn't not support tracking of the interfaces. I've done some upgrades to the IOS to the most recent versions, but still the same issue. I can make the VRRP groups with no troubles but the track command in global configuration mode doesn't appear.
I have to emphasize that we have a server behind the two routers (it is an IPTABLES in Debian) for filtering for the local network behind the server. In the Server I want to make 2 statics routes pointing to the VRRP IPs; 1 pointing to the network in the remote site and other (the default) pointing to internet. I want that the routers be able to back up each other, and I know that I can do it with VRRP or HSRP.
I have never worked with this kind of routers before and that is why I want to know if there is any c800 IOS that support HSRP or VRRP for tracking the wan interfaces in case of a failure.
Thank you giuslar for the advice, but what I've forgotten to specify is that in the track command, at least for VRRP, is based in an object number and you have to specify the object number with the track command in global configuration mode.
Router(config-if)#vrrp 1 track ?
<1-500> Tracked object
Router(config-if)#vrrp 1 track 1 decrement 30
% tracked object does not exist
And that's why you have to specify the tracked object in global configuration mode. But the command doesn't appear in global configuration mode as the guideline says.
table-map tacacs-server template tftp-server
And I got to specify too that HSRP seems to be not supported for this 850 series, because I've upgraded the IOS so many times but It's still the same history: the track command is bassed in object number, and when you try to find out the option in global configuration mode it doesn't appear. I want to know if there is any specific c850 IOS that can support HSRP or at least the track command for VRRP, or any trick to find it out or specify it.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
