Guys, I think I may be missing something here.
I've seen a couple
references to RIP being required. I didn't see that mentioned in any
of
the on-line docs. Perhaps I've missed it, and if so, I apologize.
I'll go
look at the Wiki to see if it is there.
Is this required or optional?
It is optional, but I think it will be very unpractical or even
impossible to
get the IPIP tunneling working on your SRX.
Note that it is NOT sufficient to setup a single IPIP tunnel to the
amprgw
and route all net-44 traffic over that. You need to setup a tunnel to
each
of the (about 430) gateway systems and route the defined subnets (about
615)
over those tunnels. And the IP addresses of some of the endpoints are
changing
all the time because users are on a dynamic internet IP.
To keep that config uptodate in your router, you either need to do
AMPR-RIP,
or you need to setup elaborate scripting to reconfigure the router
whenever
required. (regularly downloading the encap.txt file and generating
config for it)
In practice, you need a Linux box to do the routing, or a MikroTik
router that
has scripting powerful enough to do the above on its own.
With your SRX you will need a separate machine that does the updating.
