We currently have a problem with BGP on a 1240B running v5.0,build0322 (GA Patch 13)
We are seeing an extra local route in BGP that is breaking the default we receive from our ISP.
For now we have added a static as a work around but will need this to be reverted back to BGP asap. We have tried clearing all BGP peers "execute router clear bgp all" but it does clear the local route.
firewall (dmz) # get router info bgp network 0.0.0.0
