Hi Vishal,
Even I'm finding ipv4 address has prefix in config inventory. Could you please
cross check how apps writes into config ds?
Also, when I push the ipv6 flow without prefix, it was failing for me with
NumberFormatException and not sure how it works for Karthikeyan.
"ipv4-source": "10.10.0.4/32",
Even the model is using ipv6-prefix.
grouping "ipv6-match-fields" {
leaf ipv6-source {
description "IPv6 source address.";
type inet:ipv6-prefix;
}
leaf ipv6-destination {
description "IPv6 destination address.";
type inet:ipv6-prefix;
}
grouping "ipv4-match-fields" {
leaf ipv4-source {
description "IPv4 source address.";
type inet:ipv4-prefix;
}
leaf ipv4-destination {
description "IPv4 destination address.";
type inet:ipv4-prefix;
}
}
Regards,
Arun

Address in OXM field - Reg
Hi Arun,
Applications don't have to specify prefix length '/32' for IPv4 addresses so
why do they need to explicitly specify it for IPv6? Just as OFP defaults /32
for IPv4, can't it use /128 for IPv6 addresses?
Regards,
Vishal.
