Group -
The Arista BGP router must be configured to use its loopback address as the source address for iBGP peering sessions.
Using a loopback address as the source address offers a multitude of uses for security, access, management, and scalability of the BGP routers. It is easier to construct appropriate ingress filters...Rule Low Severity -

Group -
The MPLS router must be configured to use its loopback address as the source address for LDP peering sessions.
Using a loopback address as the source address offers a multitude of uses for security, access, management, and scalability of backbone routers. It is easier to construct appropriate ingress filter...Rule Low Severity -
SRG-NET-000512-RTR-000003
Group -
The MPLS router must be configured to synchronize IGP and LDP to minimize packet loss when an IGP adjacency is established prior to LDP peers completing label exchange.
Packet loss can occur when an IGP adjacency is established and the router begins forwarding packets using the new adjacency before the LDP label exchange completes between the peers on that link. P...Rule Low Severity -
SRG-NET-000512-RTR-000004
Group -
The MPLS router must be configured to have TTL propagation disabled.
The head end of the label-routered path (LSP), the label edge router (LER) will decrement the IP packet's time-to-live (TTL) value by one and then copy the value to the MPLS TTL field. At each labe...Rule Medium Severity -
SRG-NET-000512-RTR-000005
Group -
The PE router must be configured to have each Virtual Routing and Forwarding (VRF) instance bound to the appropriate physical or logical interfaces to maintain traffic separation between all MPLS L3VPNs.
The primary security model for an MPLS L3VPN infrastructure is traffic separation. The service provider must guarantee the customer that traffic from one VPN does not leak into another VPN or into ...Rule High Severity

The content of the drawer really is up to you. It could have form fields, definition lists, text lists, labels, charts, progress bars, etc. Spacing recommendation is 24px margins. You can put tabs in here, and can also make the drawer scrollable.
