Summary: BGP Dampening Ceiling violates RFC 2439
Product: Quagga
Version: 0.99.7
Platform: All
OS/Version: All
Status: UNCONFIRMED
Severity: major
Priority: High
Component: bgpd
AssignedTo: maintainers@quagga.net
ReportedBy: balajig81@gmail.com
The formula used for calculating Ceiling Limit(Maximum Penalty) violates the RFC
2439.
The formula used in RFC 2439 is as follows:
ceiling = reuse * (exp(T-hold/decay-half-life) * log(2))
Current Implementation
*************************
damp->ceiling = (int)(damp->reuse_limit * (pow(2,
(double)damp->max_suppress_time/damp->half_life)));
Should be changed to
*********************
damp->ceiling =
damp->reuse_limit*(exp(int)(damp->max_suppress_time/damp->half_life) * log(2))
