I have 2 876 routers which connect trough a GRE IPsec tunnel. Also the routers by default use the ISDN port as backup in case the DSL fails.
I have 2 questions
a. If a add a 3rd site do i need to configure a separate GRE tunnel/crypto map etc or just add the details of the 3rd site to my existing config?
b. I saw that through SDM i only have the option of inserting the 'dial string' of the remote site. In this scenario i need to configure dialer map for each remote site. Will it work in 876 so that the central site dial to 2 separate destinations?
Please repply if you have any info because i am troubled if i need to keep 876 for my central site or upgrade to 1841 model, which is quite expensive.
