Dear Netprof,
I am looking for a little guidance, I have a working double hub and spoke environment. A central site is connected to 5 remote sites via a circuit, a second hub site (DR) is also connected to each site. These circuits are presented by the Service Providers as two VLANs. (all based on EIGRP as routing protocol)
I now need to install backup circuits that will be either ISDN (3 sites) or ADSL (2 sites).
I am looking for advice on the best way to do this, I thinking using loopback interfaces and dialer watch. (I will be punching a hole through the firewall for connection via the internet for the adsl vpns).
Only one problem with the ISDN sites, the central site only has a single isdn circuit - so hopefully not more than one remote site would go down at a time. (maybe dialer profiles ?)
Has anyone got any advice that would be useful or any outline configs that they know are tried and tested.
Your help is appreciated.
Best regards,
Adrian.
