flexvpn dual isp spoke, how?

[dm]

Hello!

I'm absolutely newbie with FlexVPN (and never used DMVPN too), so I want to ask general question.

We need to connect to FlexVPN hub, but we have two (well, really 3 ) ISPs, and we have no our own address space, so we use addresses from IPSs pools.

I need to use one ISP as main and another as backup, with automatic switching.

btw, we have this with ASA and track and it works good enough.

Back to FlexVPN: as I see Tunnel source should be external interface, so I need to change config to switch to another ISP, i.e. it is not solvable by track.

Could you tell me recommended way to provided automatic switching for two or more ISP configuration?

btw, we plan to use CSR1000v...

Thank you!

Hi,

Here you need to create two tunnel interfaces pointing the two different tunnel sources say isp1 on tunnel 1 and isp2 on the tunnel2.... after that thr routing protocol / ip sla tracking will do the rest as usual.
