Hi Bob,

Try using the "debug-filter" options - eg, if you're debugging ospf in vrf
foo:

debug-filter ip ospf vrf foo
debug ip ospf adj

The debug-filters are really pretty powerful, it helps you narrow down the
debugs to just what you're looking for. Filters are available for most L3
protocols & infrastructure.

Hope that helps,
Tim
