DCGW routes are not programmed in CSS. Hence VM-DCGW traffic is impacted

  • Create ITM (VxLAN) between 2 DPNs. Create MPLSoGRE tunnel for CSS-DCGW
  • Configure BGP
  • Create Network, Subnet, Port via openstack and nova boot a VM
  • Configure L3VPN from COM CLI and associate the subnet to it
  • Fib entries contain the DCGW routes. However, not programmed in CSS

Observartions:

  • pcap doesn't have a flow add for table 21 DCGW routes from CSC - both CSS

MEASURES:
None
