Description of problem:
On redhat 7.1 systems configured as bgp routers, check_default_route() in
/etc/sysconfig/network-scripts/network-functions can take upwards of 5-10
minutes to execute... (think on the order of 150,000 routes...)

The obvious solution is to make check_default_route () use 'ip ro list
match 0.0.0.0/0' or something similar instead of the extremely slow and
costly piping 'route -n' into gawk.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. install redhat 7.1
2. setup zebra as a bgp peer and get 150,000 routes from another bgp peer
:-)
3. try to shutdown the box with ctrl-alt-del, go get some coffee because
its going to be a long wait... :-(
