I have configuration similar to that in the picture below.
I have main and remote offices which needed to be connecting via site-to-site vpn.
Because of an importance of traffic redundant ipsec tunnel need to be configured.
Is there any configuration which will put one of the tunnels in a standby or using some routing protocol or similar for this type of configuration.
I will appreciate if you send me some config examples or tech docs with best possible configuration.
Thank you in advance,
