Disable-Capability-Negotiation
##############################

This scenario demonstrates how to configure the disable-capability-negotiation option for a BGP neighbor.
When enabled, the router suppresses sending Capability Negotiation as an OPEN message optional parameter.
This is used for interoperability with legacy BGP implementations that do not support capability negotiation.
The test verifies that capabilities like Graceful Restart are NOT advertised when this option is enabled.

***************************************************************************
Test iBGP - Neighbor disable-capability-negotiation suppresses capabilities
***************************************************************************

Description
===========

Test to verify that disable-capability-negotiation suppresses sending BGP capabilities.
When enabled, capabilities like Graceful Restart and Route Refresh should NOT be advertised.
The session should still establish and routes should be exchanged, but in basic IPv4 unicast mode.

**************************************************
Test iBGP - Normal session advertises capabilities
**************************************************

Description
===========

Test to verify that a normal BGP session (without disable-capability-negotiation)
advertises capabilities like Graceful Restart. This serves as a baseline comparison
to confirm that disable-capability-negotiation has an observable effect.
