L2VPN Bridge Group Bridge Domain

Configure L2VPN bridge domains within bridge groups for Layer 2 Virtual Private Network services on IOS-XR devices. Bridge domains provide isolated broadcast domains within a bridge group and support EVPN, VxLAN, and interface attachments with various storm control and MTU options.
