In IOS, the assumption is that the link-local address is always constructed using Modified EUI-64 - and if it is configured manually, then it is assumed that the last 64 bits of the link-local address already contain the final Modified EUI-64 value. Therefore, if you later ask the router to configure its global prefix on the same interface

Figure 2: The IPv6 link-local address, better illustration. The better illustration of an IPv6 link-local address is: Examples: fe80::1/10, fe80:1::1/32 and fe80::1:1/64 are all IPv6 link-local addresses; their prefix lengths are 10, 32 and 64 respectively. Each such IPv6 address has the leftmost 10 bits equal to binary 1111111010. The form below does the conversion for you (both ways); Start Link-local address with 'fe80::'. Make sure you don't cut-and-paste spaces or tabs. Jan 10, 2020 · Explanation: IPv6 link-local unicast addresses are in the FE80::/10 prefix range and are not routable. They are used only for communications between devices on the same link. They are used only for communications between devices on the same link. Stack Exchange network consists of 177 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. IPv6 link-local and site-local addresses are called scoped addresses. The Windows Sockets (Winsock) API supports the sin6_scope_id member in the sockaddr_in6 structure for use with scoped addresses. For IPv6 link-local addresses (fe80::/10 prefix), the sin6_scope_id member in the sockaddr_in6 structure is the interface JUNOS also allows You to configure link local addresses with masks shorter than 64: ## Using /48 netmask [edit interfaces ge-0/0/1] regress@R1# set unit 0 family inet6 address fe80::1111:2222:3333:4444/48 [edit interfaces ge-0/0/1] regress@R1# show unit 0 { family inet { address; address; } family inet6 { address fe80::1111:2222:3333:4444/48; } } [edit interfaces

Which address is a valid IPv6 link-local unicast address?

Apr 14, 2020 What You Need to Know about IPv6 Link-Local Addresses

•Reflection • Why can the same link-local address, FE80::1, be assigned to both Ethernet interfaces on R1? Becasue they are on different subnets? global subnet? because they • What is the Subnet ID of the IPv6 unicast address 2001:db8:acad::aaaa:1234/64? • 2001:db8:acad:0 • Router Interface Summary Table Router Interface Summary Router Model Ethernet Interface #1 Ethernet Interface

Which address is a valid IPv6 link-local unicast address? Explanation: IPv6 LLAs are in the fe80::/10 range. The /10 indicates that the first 10 bits are 1111 1110 10xx xxxx. The first hextet has a range of 1111 1110 IPv4/IPv6 subnet calculator and addressing planner IPv4/IPv6 subnet calculator and hierarchical IPv6 addressing plan builder This is the online version of GestióIPv3's embedded subnet calculator.GestióIP is a free, web … Configuración de direcciones IPv6 link-local La dirección link-local FE80::1 se utiliza para que sea posible reconocer fácilmente que pertenece al router R1. Se configura la misma dirección IPv6 link-local en todas las interfaces de R1. Se puede configurar FE80::1 en cada enlace, debido a que solamente tiene que ser única en ese enlace.
