Ipv4 – IPv4 CIDR prefix or true for unnumbered IPv4 links Individual address pools are specified with these parameters: Global defaults file is topology-defaults.yml included in netlab package.Įach address pool specification is a dictionary of address pools. Local (or user) defaults file can be overwritten with -defaults option of netlab create or netlab up command. You can specify additional address pools, and use them with the pool link attribute.ĭefault IPv4 address pools are defined in system settings: Vrf_loopback pool: IPv4 and IPv6 prefixes used on optional VRF loopback interfaces. See layer-2-only pools and Using l2only Address Pool for details. L2only pool has no IPv4 or IPv6 addresses. Router_id pool is used to allocate BGP router IDs in IPv6-only networks. P2p pool: IPv4 and IPv6 addresses used on point-to-point links Lan pool: IPv4 and IPv6 addresses used all links apart from P2P links (links with more or less than two nodes attached to them), or links with type set to lan. Loopback pool: Loopback IPv4 and IPv6 addresses. IPv6 addresses are assigned if specified, but not used at the moment.

Mgmt pool: Management IPv4 and MAC addresses. Netlab use multiple predefined address pools: For more details, see static link addressing. You can assign a static prefix to a link with prefix link attribute and static IP address to an interface with an ipv4 or ipv6 attribute of node-on-link data.

A block of private or local addresses is defined, which is the set of all addresses beginning with ∱111 1110 1 as the first nine bits. The unspecified address, 0:0:0:0:0:0:0:0 (:: in compressed form) is used to indicate an unknown address. Key Concept: In IPv6, a special loopback address, 0:0:0:0:0:0:0:1 (::1 in compressed form) is set aside for testing purposes. Is all zeroes, the address becomes just ::. Zero compression can be applied to this address since it Source field of a datagram sent by a device seeking to have its IP addressĬonfigured. In IPv6 thisĬoncept has been formalized, and the all-zeroes address (0:0:0:0:0:0:0:0) Is 0:0:0:0:0:0:0:1, which is normally expressed using zero compressionĪnd is used when a device doesn't know its own address.
(which was never needed in the first place, really!) The loopback address IPv6 there is just one address for this function, not a whole block This address loop back to the sending device. TheseĪddresses are further divided into two types based on their scope, described With the next hex digit being from ∸ to ∿. Private addresses have a first octet value of ∿E in hexadecimal, The address having "1111 1110 1 for the first nine bits. Never routed outside a particular company's network. These privateĪddresses are local only to a particular link or site and are therefore In IPv6 the private address block in IPv6 is much larger.
