Static Virtual Tunnels Interfaces (SVTI)

[karen_mcalister]

Hi, I need some help in guiding me in how to apply SVTI for 60+ tunnels over a single interface. (i.e source and destination are the same for all tunnels s = 10.0.0.1 and dest = 10.0.0.2. When I try to create more than one tunnel, the first tunnel goes down.

Karen,

Yep - you have hit the first show stopper with multiple tunnels using the same IP scheme!

I have 115 tunnels from my D/C's going to remote sites - no issues, as I have allocated specific IP address ranges.

My tunnels have specific /30 addresses out of a /24 range. I use loopback's for source & destination's for the tunnels - the loopbacks are part of their own /24 with 255.255.255.255 subnet masks.

To be honest if you have planned your IP subnet structure correctly - you should have no issues giving your 60+ tunnels unique ip addresses.

HTH.
