The command is: ip dhcp database url [timeout seconds | write-delay seconds] and the following are the acceptable URL file formats: - tftp://host/filename - ftp://user:password@host/filename - rcp://user@host/filename Make sure you have enabled "ip dhcp conflict logging". You can find out more at this URL (but the detail is kind of light): http://www.cisco.com/en/US/products/sw/iosswrel/ps1835/products_configuration_guide_chapter09186a00800ca75c.html You apply this command to both routers. I'm not sure (because I've not done this before) what happens when the database agent is lost and comes back but in between that, the router continues to hand out IP addresses. Do the routers update the database agent of changes during the outage? If so, how are conflicts then handled? It would be neat if someone who've done this can advise. ... View more

Further to this thread ... I agree it certainly is possible to have both routers providing DHCP service as long as the scope is split, each router having a different DHCP scope (pool) to the other. What if the pool has to be identical because the number of devices far outweigh the available IP space if the scope was split in half? Theoretically speaking if you set up a remote database agent, then both routers will write their bindings to that database. That way both routers can be configured with identical pools, and conflict resolution can be determined via the common database. The question I have is what happens if connectoivity to the database agent is lost or the database agent is down. Will the routers still respond to DHCP requests and allocate IP addresses, but not write to the database agent? What happens when the database agent comes back? Does anyone have experience here? ...

No particular purpose. It was to better understand whether the tunnel behaved similarly to a regular interface in IPv6, given that in IPv6 you can assign multiple IPv6 addresses to an interface. ... View more
