Re: [vpp-dev] multiple ips for an interface
Hi Ole, Yea, i have my routes on the "show ip6 fib", but still even ping did not work. I tried to ping the ips assigned to the local ports on vpp, -> did not work tried ip4, still did not work. I could not figure out what "Configuration" i am missing here.

Re: [vpp-dev] multiple ips for an interface
Hi Ole, I am just trying to send and receive ip6 traffic through the vpp. I configured the ports with ip6 addresses and send traffic as below. But it was not forwarded to the destination port 2.

Re: [vpp-dev] multiple ips for an interface
Pragash, > Is there any cli command for source address selection in the vpp? No. Source address selection only comes into play for locally originated packets. VPP itself has only a few of those, and they are somewhat special case. Like ND for example. An application could use ip_address_dump/ip_address_details APIs and then follow the algorithm in RFC6724/RFC8028. But before we talk about solutions, what problem are you trying to solve?
