Hello Gurus,
I am a networking newbie, working on a project to upgrade the current
VPN gateway in my company.
Here's the scenario:
I have a VPN gateway at a remote site which I would call as C.
There are two VPN gatewy's A and B at my current site.
B is the main gateway and A is a backup in case B fails.
I have setup Site-to-Site Tunnels on all these gatewyas with
appropriate security associations.
I am using the IPSEc security profile.
C has tunnels to both A and B.B tunnel has metric 0 and A has metric on
1.
B has a tunnel to C and knows that its failover option is A.
I have tested the tunnels manually and they seem to work fine.
My question to you guys, Currenlty I setup a static route on the core
at the current site to route all traffic to C through VPN gateway B. In
case of B failing, I will have to manually change this route to go
through VPN A.
Is there a way by which I could automate this routing change?
I am using Shiva 3115 VPN gateways and they have an option to configure
OSPF.
Do I need to setup dynamic routing on the VPN gateways or on the main
core?And how?
Thank you in advance.
