However, the computer can still access the local network and the internet through the IPv4 protocol.IPv6 is the next version of the networking protocol to overcome the limitations of IPv4. Primarily, the new version of the protocol deals with the shortage of IP addresses, as IPv4 uses a 32-bit address scheme that offers close to 4.3 billion, and IPv6 uses a 128-bit address scheme that provides trillions of addresses. However, since the transition has been slower than expected, operating systems like Windows run both network stacks simultaneously.Typically, you should keep the IPv6 protocol enabled, but you may find times when to disable it. However, if you are experiencing networking issues, it's probably because the protocol has been disabled, in which case, turning it on again may resolve the issue.More resourcesFor more helpful articles, coverage, and answers to common questions about Windows 10 and Windows 11, visit the following resources:Windows 11 on Windows Central — All you need to knowWindows 10 on Windows Central — All you need to knowMauro Huculak has been a Windows How-To Expert contributor for WindowsCentral.com for nearly a decade and has over 15 years of experience writing comprehensive guides.

Below. Figure 8. L2VPN Xconnect Service Over Segment Routing The topology represents an L2VPN Xconnect service over a Segment Routing core setup. By default, Xconnect uses tLDP to signal service labels to remote PEs. By default, tLDP not only signals the service label, but also known (IPv4 and IPv6) label bindings to the tLDP peer, which is not required. The LDP SAC capabilities is an optional configuration enabled under LDP, and users can block IPv4 and IPv6 label bindings by applying configurations on PE1 and PE2. Configuration PE1 Configuration Disable IPv4 prefix LSP binding advertisements on PE1: PE1(config)# mpls ldp capabilities sac ipv4-disable PE1(config)# commit Disable IPv6-prefix LSP binding advertisements on PE1: PE1(config)# mpls ldp capabilities sac ipv4-disable ipv6-disablePE1(config)# commit Note Whenever you disable a non-negotiated LDP application state on a router, you must include previously disabled non-negotiated LDP applications too, in the same command line. If not, the latest configuration overwrites the existing ones. You can see that ipv4-disable is added again, though it was already disabled.

Integrated into Cisco IOS Release 12.2(33)SRB. 12.2(33)SXH This command was integrated into Cisco IOS Release 12.2(33)SXH. Cisco IOS XE Release 2.1 This command was introduced on Cisco ASR 1000 Series Routers. Usage Guidelines For networks that include links over X.25 packet-switched networks (PSNs), you can use the neighbor command in router configuration mode to disable the split horizon feature. Or, you can specify the no ipv6 split-horizon eigrp command in your configuration. However, if you do disable the split horizon feature, you must similarly disable split horizon for all routers and access servers in any relevant multicast groups on that network. Note In general, we recommend that you not change the default state of split horizon unless you are certain that your application requires the change in order to advertise routes properly. Remember that if split horizon is disabled on a serial interface and that interface is attached to a packet-switched network, you must disable split horizon for all routers and access servers in any relevant multicast groups on that network. Examples The following example disables split horizon on a serial link connected to an X.25 network: interface serial 0 encapsulation x25 no ipv6 split-horizon eigrp 101 Related Commands Command Description neighbor (EIGRP) Defines a neighboring router with which to exchange routing information on a router that is running EIGRP. ipv6 summary-address eigrp To configure a summary aggregate address for a specified interface, use the ipv6 summary-address eigrp command in interface configuration mode.

(Never use this network for default route)By default any gateway we add for any ethernet connection will also be considered as default gateway, to turn off this directive use ipv4.never-default with nmcliBefore we make any change verify DEFROUTE directive in the eth2 configuration file# egrep '^DEFROUTE' /etc/sysconfig/network-scripts/ifcfg-eth2DEFROUTE=yesSo by default this directive is ON, we will disable the default gateway option for eth2. To turn off this directive we must select ipv4.never-default as "yes"# nmcli con mod eth2 ipv4.never-default yesNext verify the DEFROUTE directive for eth2# egrep '^DEFROUTE' /etc/sysconfig/network-scripts/ifcfg-eth2DEFROUTE=no18. Disable IPv6 Address for ethernet connection (IPV6INIT)By default both IPv4 and IPv6 connection type (IPV6INIT) is enabled for any ethernet connection type. To only use IPv4 and disable IPv6 using nmcliVerify the existing status of IPv6 connection type for eth2# egrep 'IPV6INIT' /etc/sysconfig/network-scripts/ifcfg-eth2IPV6INIT=yesSo this is enabled, we will disable IPv6 connection type using ipv6.method directive with nmcli# nmcli con mod eth2 ipv6.method ignoreHINT:Supported input arguments for ipv6.method are ignore, auto, dhcp, link-local, manual, shared. You can use the same options to enable/disable IPv4 using ipv4.methodNow re-verify the IPV6INIT directive from eth2 config file# egrep 'IPV6INIT' /etc/sysconfig/network-scripts/ifcfg-eth2IPV6INIT=no19. Change "Automatically Connect" DirectiveBy default any ethernet connection will be allowed to automatically connect, you can modify this using# nmcli con mod eth2 connection.autoconnect no20. Add or Modify DNS to existing connectionYou can use ipv4.dns to add DNS server to an new connection or modify any existing connection using nmcli.Currently there are no DNS server IP provided for eth1# egrep DNS /etc/sysconfig/network-scripts/ifcfg-eth1Next modify connection to add DNS Server IP Address# nmcli con mod eth1 ipv4.dns 8.8.8.8Verify the eth1 config file[root@rhel-8 ~]# egrep DNS /etc/sysconfig/network-scripts/ifcfg-eth1DNS1=8.8.8.821. Append single/multiple DNS Server to connectionUse + prefix with ipv4.dns to append new DNS IP Addresses to an existing connection using nmcli. In the previous example we added 8.8.8.8 as my DNS server for eth1. Now we will append 8.2.2.2 to the same connection# nmcli con mod eth1 +ipv4.dns 8.2.2.2Verify the eth1 configuration file# egrep DNS /etc/sysconfig/network-scripts/ifcfg-eth1DNS1=8.8.8.8DNS2=8.2.2.2HINT:You can also append single or multiple values from other multi-value (container) properties like ipv4.dns, ipv4.addresses, bond.options, etc22.
