[VRRP] vrrp faster backup

[liu.zhiwei1 at zte.com.cn]

Dear All

I'm a new comer in IETF.

VRRP [RFC 3768] specifies an election protocol that dynamically
assigns responsibility for a virtual router to one of the VRRP routers
on a LAN. 
This election process provides dynamic fail  over
in the forwarding responsibility should the Master become unavailable.

   
The router survivability capability provided by the Virtual
Router Redundancy Protocol requirement: (3 * Master_Adver_Interval) + Skew_timer
for  Backup Router to declare Masterdown in the VRRP [RFC 3768].
It will be more than 3 second when the Master_Adver_Interval
was 1 second. 
In some LAN environments, the Backup Router needs faster
method to declare the Master Router is fail.
As if (2 * Master_Adver_Interval) + Skew_timer or (1 *
Master_Adver_Interval) + Skew_timer. 
Are there a message type which permits the Backup Router
could backup faster?
 
Best Regards
