Re: draft-ietf-vrrp-unified-mib-06: Usage of vrrpTrapProtoError

Hi Kaylan,

I propose that vrrpTrapProtoErrorEnable should be disabled by default.  The
operator can then turn this on if (s)he cares about receiving this trap.  On
a scaled system with numerous interfaces configured with multiple VRRPs,
these traps will have a big impact and we won't be able to maintain
sub-second timers as recommended by the VRRP draft.

Regards,
Georges Chung
