[show] vnet advertised-route command (sonic-net#2390)
What I did Added a new show command to see the VNET Tunnel routes being advertised by BGP. The output can be filtered based on IPv4/Ipv6 and community string. How I did it Iterate over the BGP_PROFILE_TABLE in Application DB and ADVERTISE_NETWORK_TABLE in state DB. Correlate the information and filter based on community string. How to verify it run **show vnet advertised-routes ** with optional community string. $ show vnet advertised-route Prefix Profile Community Id ------------------------ ------------------- -------------- 160.62.191.1/32 FROM_SDN_SLB_ROUTES 1234:1235 160.63.191.1/32 FROM_SDN_SLB_ROUTES 1234:1235 160.64.191.1/32 FROM_SDN_SLB_ROUTES 1234:1235 fccc:a250:a251::a6:1/128 fddd:a150:a251::a6:1/128 FROM_SDN_SLB_ROUTES 1234:1235 $ show vnet advertised-route 1234:1235 Prefix Profile Community Id ------------------------ ------------------- -------------- 160.62.191.1/32 FROM_SDN_SLB_ROUTES 1234:1235 160.63.191.1/32 FROM_SDN_SLB_ROUTES 1234:1235 160.64.191.1/32 FROM_SDN_SLB_ROUTES 1234:1235 fddd:a150:a251::a6:1/128 FROM_SDN_SLB_ROUTES 1234:1235
