.. _example_protocols_bgp_peer-group_capability-negotiation: ###################### Capability-Negotiation ###################### Scenario to verify BGP **peer-group capability negotiation** features. BGP capabilities are negotiated during session establishment to determine what features both peers support. The ``disable-capability-negotiation`` option suppresses sending capabilities in the OPEN message, so the peer only sees the capabilities it receives (e.g., Graceful Restart shows as "received" only instead of "advertised and received"). The ``override-capability`` option forces session establishment even when there is a capability mismatch between peers (e.g., one peer activates IPv6 but the other does not). Without ``override-capability``, a peer configured with ``strict-capability-match`` will reject sessions when capabilities do not match. When configured on a peer-group, all members inherit the capability negotiation behavior. ********************************************* Test iBGP - Peer-group capability negotiation ********************************************* Description =========== Test ``disable-capability-negotiation`` and ``override-capability`` on a peer-group.
