What is IPv6 RA guard?

What is IPv6 RA guard?

The IPv6 RA Guard feature provides support for allowing the network administrator to block or reject unwanted or rogue RA guard messages that arrive at the network device platform. RAs are used by devices to announce themselves on the link. In host mode, all RA and router redirect messages are disallowed on the port.

How do I enable IPv6 configuration?

Enable IPv6

1. Select Network > Interfaces. The Network Interfaces page appears.
2. Select an external interface. Click Configure. The Interface Settings dialog box appears.
3. Select the IPv6 tab.
4. Select the Enable IPv6 check box.

What is IPv6 ND suppress RA?

Disables the sending of router advertisement messages on an interface.

What is IPv6 ND inspection?

IPv6 ND inspection is an internal network security system that detects and prevents IPv6 address spoofing at the switch level. IP communication within a Layer 2 infrastructure is established by mapping an IP address to a MAC address.

How does IPv6 RA work?

The RA contains the network part of the Layer 3 IPv6 address (IPv6 Prefix). The host uses the IPv6 prefix provided by the RA; generates the universally unique host part of the address (interface identifier), and combines the two to derive the complete address.

What is RA message?

Enabling or disabling router-advertisement (RA) messages enables you to control the routing configuration for selecting the correct network interface to communicate with its neighbors.

Should IPv6 be enabled?

Best answer: IPv6 can potentially add support for more devices, better security, and more efficient connections. While some older software may not work as expected, most of your network should work fine with IPv6 enabled.

How do I know if IPv6 is enabled?

Check connection status

1. For wired connection through a router, right-click “Ethernet”, and for wireless connection right-click “Wi-Fi”, and then click “Status”.
2. Click “Details”.
3. If you see an IP address for IPv6 within the window marked with a red box, you are connected to the IPv6 network.

What is IPv6 managed config flag?

The ipv6 nd managed-config-flag sets a flag in the router advertisement that tells the hosts that they could use DHCPv6. The last command that ends with no-autoconfig tells the hosts not to use stateless configuration.

What does the nd other flag configure on a router?

Other-Config-Flag tells the end-host to use SLAAC to get IPv6 address and DHCPv6 to get other parameters (DNS server address, for example). Absence of both flags tells the end-host to use only SLAAC.

What is RA service?

RA Services means recovery audit services or contract compliance services provided by Purchaser Parent or its subsidiaries.

What is RA setting?

Do you enable RA Guard on a Cisco wireless LAN controller?

By default, RA guard is enabled at the AP (but can be disabled) and is always enabled on the controller. Dropping RAs at the AP is preferred as it is a more scalable solution and provides enhanced per-client RA drop counters.

What is the IPv6 source guard feature in Cisco?

The IPv6 source guard feature prevents a wireless client spoofing an IPv6 address of another client. This feature is analogous to IPv4 source guard. IPv6 source guard is enabled by default.

How does the DHCPv6 server guard protect the network?

In all cases, the IPv6 RA is dropped at some point, protecting other wireless clients and upstream wired network from malicious or misconfigured IPv6 clients. The DHCPv6 Server guard feature prevents wireless clients from handing out IPv6 addresses to other wireless clients or wired clients upstream.

How does a wireless LAN controller support IPv6?

To enable wireless IPv6 client connectivity, the underlying wired network must support IPv6 routing and an address assignment mechanism such as SLAAC or DHCPv6. The wireless LAN controller must have L2 adjacency to the IPv6 router, and the VLAN must be tagged when entering the controller interfaces.
