a routing question

hi team,

i have a scenario,

isp.......routerB......mpls/BGP.......router A.....firewall.....dsl...isp

routeb, needs to act as a failover for A internet traffic
router A, only has a static route to Firewall interface,
routerA, will never detect the the dsl link down, since it is on another
subnet
so no matter what router B advertise, floting static..default
originate....etc
it willl be no good for A, it can see that in the table, looks good, but
will never be activated as a another default route, since A always will
see the static route to firewall, and it looks fine as far as the router
a can tell,
how can you change that,
without
enable a routing protocol on the firewall, in another words, without
doing any changes on the firewall ?

cheers

JT
