Jinja2 Filters

IP address

napalm_yang.jinja_filters.ip_filters.cidr_to_netmask(value, *args, **kwargs)

Converts a CIDR prefix-length to a network mask.

Examples

>>> "{{ '24'|cidr_to_netmask }}" -> "255.255.255.0"

napalm_yang.jinja_filters.ip_filters.netmask_to_cidr(value, *args, **kwargs)

Converts a network mask to it’s CIDR value.

Examples

>>> "{{ '255.255.255.0'|netmask_to_cidr }}" -> "24"

napalm_yang.jinja_filters.ip_filters.normalize_address(value, *args, **kwargs)

Converts an IPv4 or IPv6 address writen in various formats to a standard textual representation.

This filter works only on addresses without network mask. Use normalize_prefix to normalize networks.

Examples

>>> "{{ '192.168.0.1'|normalize_address }}" -> "192.168.0.1"
>>> "{{ '192.168.1'|normalize_address }}" -> "192.168.0.1"
>>> "{{ '2001:DB8:0:0:1:0:0:1'|normalize_address }}" -> "2001:db8::1:0:0:1"

napalm_yang.jinja_filters.ip_filters.normalize_prefix(value, *args, **kwargs)

Converts an IPv4 or IPv6 prefix writen in various formats to its CIDR representation.

This filter works only on prefixes. Use normalize_address if you wish to normalize an address without a network mask.

Examples

>>> "{{ '192.168.0.0 255.255.255.0'|normalize_prefix }}" -> "192.168.0.0/24"
>>> "{{ '192.168/255.255.255.0'|normalize_prefix }}" -> "192.168.0.0/24"
>>> "{{ '2001:DB8:0:0:1:0:0:1/64'|normalize_prefix }}" -> "2001:db8::1:0:0:1/64"

napalm_yang.jinja_filters.ip_filters.prefix_to_addrmask(value, *args, **kwargs)

Converts a CIDR formatted prefix into an address netmask representation. Argument sep specifies the separator between the address and netmask parts. By default it’s a single space.

Examples

>>> "{{ '192.168.0.1/24|prefix_to_addrmask }}" -> "192.168.0.1 255.255.255.0"
>>> "{{ '192.168.0.1/24|prefix_to_addrmask('/') }}" -> "192.168.0.1/255.255.255.0"
