[j-nsp] Alternatives to floating static routes?

[Dario]

Hi all,

We need to develop a solution to provide redundancy for two of our clientes, connected to us via our 
Cisco Catalyst 2950.

This is the topology:
                                  [FastEth]
	Router Customer 1	------------- |                   [GigaEth]
					         |  Cat 2950 --------------- Juniper M40e
	Router Customer 2	------------- |              
                                  [FastEth]

Right now we have static routes in our Juniper to connect with each customer. The customers have the
posibility to connect their routers. Each one request us to reroute its networks via the other customer when
its link fails.

We first think in floating static routes, two routes for each customer, the actual one and other via the 
other customer with more metric.

But it'll no work because if for example the link between the Customer 1 and our CAT 2950 fails, our 
Juniper see the link with the CAT 2950 up (no possibility to configure keepalives), then the active route 
is the static route without metric, it never changes to the floating route.

BGP (using prepends,...) is a solution but we prefer another one if possible. Any ideas?

Many thanks and best regards,

	Dario D.
