Looking Glass

The Looking Glass is a GUI-based tool for looking up routing information from a switch or SoftGate perspective. You can access the Looking Glass either from Topology, individually for every device (right click on device → details → Looking Glass), or by navigating to Network → Looking Glass then selecting the device from the top-left dropdown menu.

Looking Glass controls described for IPv4/IPv6 protocol families.

  • VPC - select a VPC.

  • BGP Summary - Shows the summary of BGP adjacencies with neighbors, interface names, prefixes received. You can click on the neighbor name then query for the list of advertised/received prefixes.

  • BGP Route - Lookup the BGP table (RIB) for the given address.

  • Route - Lookup switch routing table for the given address.

  • Traceroute - Conduct a traceroute from the selected device towards the given destination, optionally allowing to determine the source IP address.

  • Ping - Execute a ping on the selected device towards the given destination, optionally allowing to select the source IP address.

Example: listing BGP neighbors of a switch and number of received prefixes for the Underlay VPC.

Example: BGP Route - looking up V-Net subnet from switch11 perspective. Switch11 is load balancing between four available paths.

Looking Glass controls described for the EVPN family.

  • VPC - select a VPC.

  • BGP Summary - Show brief summary of BGP adjacencies with neighbors, interface names, and EVPN prefixes received.

  • VNI - List VNIs learned.

  • BGP EVPN - List detailed EVPN routing information optionally for the given route distinguisher.

  • MAC table - List MAC address table for the given VNI.

Example: Listing MAC addresses on VNI 50.
