add a static default route for both circuits pointing to Level 3.  You can have one of the routes with a higher cost.  Make sure the default static routes get redistributed through your IGP.

then turn off bgp .

drink lots of coffee when you do this at 2am  :)

Subject: [isp-bgp] question about stopping bgp


we are a local ISP and are currently running bgp-4 with our upstream
provider on two 100 mbit ethernet interfaces ( for redundant cabling and
port purposes) on our single borderrouter, connecting to 2 different routers
at the same upstream provider, which is Level3	
-----------------------------
      Level3
router1	router2
I		I
I		I 
ethernet1	ethernet2		 
I		I
----------------
borderrouter
----------------

we used to have another provider, which we cancelled and thus I think it
makes no more sense to use BGP-4, since we could not care less, how the
routing is done within this upstream provider and how he announces our own
AS to the rest of the world..we are getting full tables from them..which is
eating up cpu/memory...

so the idea is, to stop BGP for the sake of saving cpu and memory on the
borderrouter and change to static routes with a priority metric..

strange enough I am not 100% sure, if this is the best way and if so, how to
do it in an orderly manner..especially the metrics to define a primary
working and a standby port..setting up BGP was easier  :-)

any hints how to do it safely ( of course our backbone provider has to do it
simultaneously) 
any help is appreciated, since I am pretty scared to drive us offline with a
tiny mistake..
