Can link local addresses be routed?

Can link local addresses be routed?

Link-local addresses are not guaranteed to be unique beyond their network segment, therefore routers do not forward packets with link-local source or destination addresses.

How do you set a link-local IPv6 address on a router?

Configuring a link-local IPv6 address on an interface

1. Enter global configuration mode. device# configure terminal.
2. Enter interface configuration mode. device(config)# interface ethernet 3/1.
3. Configure a link-local IPv6 address for the interface. device(config-if-e1000-3/1)# ipv6 address FE80::240:D0FF:FE48:4672 link-local.

What is the purpose of a link local address?

These addresses refer only to a particular physical link and are used for addressing on a single link for purposes such as automatic address configuration and neighbor discovery protocol. Link-local addresses can be used to reach the neighboring nodes attached to the same link.

What is the range for an IPv6 link-local address?

10 to 127
The length of the prefix of an IPv6 link-local address ranges from 10 to 127.

How do I ping a link with a local address?

To test the link-local address:

1. Use ping 8.8. 8.8 to ping an Internet host by IP address.
2. Observe the results. The ping request should fail, because link-local addresses do not have a default gateway assigned and are not routable to the Internet.

How are link local addresses used in IPv6?

Introduction. Link-local addresses can be used to reach the neighboring nodes attached to the same link. The nodes do not need a globally unique address to communicate. Routers will not forward datagram using link-local addresses. IPv6 routers must not forward packets that have link-local source or destination addresses to other links.

Do you need a globally unique IPv6 address?

The nodes do not need a globally unique address to communicate. Routers will not forward datagram using link-local addresses. IPv6 routers must not forward packets that have link-local source or destination addresses to other links.

Can a link local address be routed to a public network?

Link-local addresses cannot be routed to public networks and limited to the local network. Link-local addresses are auto-configured (or auto-generated plug-and-play) addresses (Stateless addresses) similar to IPv4 APIPA addresses (169.254.0.0/16).

What is the difference between IPv6 link local address and global unicast address?

Here is a link to a video (available on Cisco Support Community) that demonstrates the key difference between the IPv6 Link-Local Address and global unicast address in Cisco IOS routers: ! hostname R1 ! ipv6 cef ! ipv6 unicast-routing ! interface Loopback10 no ip address ipv6 address 2010::/64 eui-64 !—
