IPv6 in CLI

Questa guida descrive come creare una rete IPv6 o dual-stack utilizzando la CLI OpenStack.

Prerequisiti

  • Application Credentials (clouds.yaml) configurate (vedere Tools).
  • IPv6 è attualmente limitato alla regione 2 (ch-ge1).

Creare un router

openstack router create test-router1 --external-gateway public

Visualizzare il pool di sottoreti IPv6 disponibile

openstack subnet pool list --share | grep tenant-subnet-pool-v6

Creare una rete

openstack network create test-network1

DUAL-STACK: creare una sottorete IPv4 (saltare per solo IPv6)

openstack subnet create test-subnet1-ipv4 \
    --network test-network1 \
    --subnet-range 10.11.12.0/24

DUAL-STACK: collegare la sottorete IPv4 al router (saltare per solo IPv6)

openstack router add subnet test-router1 test-subnet1-ipv4

Creare una sottorete IPv6

openstack subnet create test-subnet1-ipv6 \
    --network test-network1 \
    --ip-version 6 \
    --subnet-pool external-subnet-pool-v6 \
    --prefix-length 64 \
    --ipv6-ra-mode dhcpv6-stateless \
    --ipv6-address-mode dhcpv6-stateless

Collegare la sottorete IPv6 al router

openstack router add subnet test-router1 test-subnet1-ipv6

OPZIONALE: creare un security group e delle regole

SECURITY_GROUP=test-secgroup
openstack security group create ${SECURITY_GROUP}

DUAL-STACK: consentire l'accesso IPv4 (saltare per solo IPv6)

openstack security group rule create ${SECURITY_GROUP} --ethertype IPv4 --protocol icmp --ingress --remote-ip 0.0.0.0/0
openstack security group rule create ${SECURITY_GROUP} --ethertype IPv4 --protocol icmp --egress --remote-ip 0.0.0.0/0
openstack security group rule create ${SECURITY_GROUP} --ethertype IPv4 --protocol tcp --dst-port 22 --remote-ip 0.0.0.0/0
openstack security group rule create ${SECURITY_GROUP} --ethertype IPv4 --protocol tcp --dst-port 80 --remote-ip 0.0.0.0/0

Consentire l'accesso IPv6

openstack security group rule create ${SECURITY_GROUP} --ethertype IPv6 --protocol ipv6-icmp --ingress --remote-ip "::/0"
openstack security group rule create ${SECURITY_GROUP} --ethertype IPv6 --protocol ipv6-icmp --egress --remote-ip "::/0"
openstack security group rule create ${SECURITY_GROUP} --ethertype IPv6 --protocol tcp --dst-port 22 --remote-ip "::/0"
openstack security group rule create ${SECURITY_GROUP} --ethertype IPv6 --protocol tcp --dst-port 80 --remote-ip "::/0"

Creare una VM di test

SERVER_ID=test-vm1-test
openstack server create ${SERVER_ID} \
    --flavor m1.small \
    --image "Ubuntu 24.04" \
    --network test-network1 \
    --key-name test-key \
    --security-group ${SECURITY_GROUP}

DUAL-STACK: assegnare una floating IP IPv4 (saltare per solo IPv6)

FLOATING_IP=$(openstack floating ip create public -c floating_ip_address -f value)
openstack server add floating ip ${SERVER_ID} ${FLOATING_IP}

Visualizzare gli indirizzi IP

openstack server show ${SERVER_ID} -c addresses
