Does P4Utils Support IPv6 ？

[liudsl]

Hi everyone:

I want to do something about SRv6, specifically using BMV2 to implement SRv6, but I found that the function net.setIntfIp() cannot set the IPv6 address for host. How should I solve it?

Thank you very much!

here is my code:

#! /usr/bin/python3

net = NetworkAPI()

# Network general options
net.setLogLevel('info')
net.enableCli()

# Network definition
net.addSwitch("s1")
net.addHost('h1')
net.addHost('h2')

net.addLink('h1', 's1', port2=1)
net.addLink('s1', 'h2', port1=2)

net.setIntfIp("h1", "s1", "2001:db00::0/24")
# Assignment strategy
# net.l2()

# Nodes general options
net.enableLogAll()

# Start the network
net.startNetwork()

And Here is the output after sudo python3 network:

.......
Topology saved to disk!

Switches programmed correctly!
Programming hosts...

Traceback (most recent call last):

@liudsl Unfortunately, for most features we do not have support for IPv6.

To solve it you would need to adapt the code in all the placers where we assume addresses are IPv4.

@huyongqingandczw Why do you write your question in this git issue thread, I don't think what you are asking has anything to do with the original question. Can you please not do that?

If your question is unrelated to the current thread, I kindly suggest creating a new issue or finding a thread that aligns more closely with your topic.

Hello @liudsl what did you do to solve that?
