Auto-add physical interfaces for BGP and EIGRP peer connections

NetBrain currently does not automatically identify or add the physical interfaces that interconnect devices participating in a BGP or EIGRP peering relationship when those devices are added to a map. Users must manually determine and add the correct physical interfaces to represent the underlying Layer 2 connectivity between routing protocol peers. This enhancement would allow NetBrain to detect BGP or EIGRP peer relationships between devices on a map and automatically add the physical interfaces that logically interconnect them. Customers with routing-protocol-driven topologies would gain more accurate and complete maps with reduced manual effort, improving topology accuracy and troubleshooting efficiency.
