[j-nsp] IPsec to VRRP - redundant tunnels

[Massimiliano Galizia]

(I'm sorry if received it twice... got some problems with mail server)

Hello ML,
I have a network scenario like this below:

[M7i]--|
          |---WAN---[Cisco]
[M7i]--|

Between Cisco and both JNPR I have to establish IPsec tunnels, one for
each M7i. Configurations work great, but I have a problem: how to make
Cisco router discover a faulty M7i and the redundant M7i take up the
IPsec tunnel?  First, I thought to  configure the DPD on Cisco ( IKE
keepalive). When Cisco doesn't receive a: "R_U_THERE" hello answer, it
should engage the second end-point: did you ever tried this?, does it
work?

The second possibility is to make the Cisco establish IPsec tunnel to
a VRRP address: once again, do yuo have some experience about this?
Thnks a lot for your patience and help.

Ciao
