Description:

As a network administrator, I would like OpenShift to support optimized BGP route advertisement by automatically aggregating contiguous IP prefixes into summarized routes when possible.

Currently, OpenShift advertises each individual subnet (e.g., /24), even when those subnets are part of a contiguous range. This leads to unnecessarily large BGP routing tables, which increases processing overhead on routers and can impact convergence times in larger environments.

Use Case / Examples:

Simple Aggregation Example:

Instead of advertising:

192.168.0.0/24

192.168.1.0/24

OpenShift should be capable of advertising the aggregated prefix:

192.168.0.0/23

Larger Aggregation Example:

Given the following subnets:

192.168.0.0/24  

192.168.1.0/24

192.168.2.0/24

192.168.3.0/24

192.168.4.0/24

192.168.5.0/24

192.168.6.0/24

192.168.7.0/24

Instead of advertising 8 separate /24 routes, OpenShift should aggregate and advertise:

192.168.0.0/22  

192.168.4.0/22
