pass eigrp info between a 0pix-router ipsec vpn

[c99wayne]

Greetings,

We have a local PIX515R VPN tunnel with a remtoe vpn router.
(connected via a ipsec vpn tunnel via the Internet)

We want to rotue eigrp thru' this vpn tunnel.

Both the local lan and the remote lan are running eigrp.

But PIX can't route eigrp.

Does anyone see a workaround that I can reference with?

I have heard gre tunnel with loopback addresses on the remote vpn router and a router behind the PIX. I tried without success.

thanks in advance for any hints.

regards / Wayne.

Wayne,

Even if the PIX could route EIGRP you would still be out of luck. EIGRP uses multicast to propagate routing updates and IPsec doesn't do multicast (It creates unicast tunnels).

I suggest you take a look at GRE tunnelling. If you create a GRE tunnel between the two networks you can pass that GRE tunnel (from a router) inside of an IPsec tunnel (from the PIX).

It works great!

Liberty for All,

Brian
