Question What is the behavior of a virtual tunnel interface in different services routing instances?
Question Which components are used in calculating the load balancing (hashing) algorithm for a link aggregation group? Answer For Layer 3 traffic, the default components used to calculate the load balancing (hashing) algorithm for a link aggregation group (LAG) are the source address, destination address, and interface indexes
Question What are the differences in packet processing between a VT interface and an LSI interface (vrf-table-label or no-tunnel-services)? Answer The LSI interface provides better packet processing performance than the VT interface, unless there are core-facing interface restrictions or loss of ingress forwarding functionality, because the frame is sent only once through the route lookup. In a VT interface, the packet loops back, with a first pass as mpls-vrf and a second pass for frame processing. The VT interface is limited by an overall tunnel bandwidth of 1/10 Gbps. The LSI interface is limited by line rate
Question How can I define multiple port mirroring interfaces on a single chassis and select which traffic is mirrored to each interface on MX Series routers?...All platforms support multiple source ports (interfaces that need to be mirrored)
