Hi VPP experts,

I would like to shed light on a particular scenario/usecase that I'm trying to 
implement in VPP.

The scenario demands egress packet routing to be done based on the source IP of 
the packet rather than the destination IP. I found a similar discussion in the 
VPP mail archive( https://www.mail- archive.com/[email protected]. 
io/msg06886.html ( 
https://www.mail-archive.com/[email protected]/msg06886.html ) ), but the 
solution discussed there would not be applicable for routing multiple source IP 
packets having different routes.

I understand that we can configure multiple routing table in VPP with unique 
routes in them, but would I be able to make the FIB lookup towards a particular 
table based on source IP?

If I take an analogy from Linux kernel, does VPP support functionality similar 
to 'ip rule' command, wherein we can specify a routing table to be used for a 
particular source IP.

Looking forward to your advice and support in finding a solution to this. 

Thanks & Regards,
Georgi
