description:

This module provides Scapy layers for the Intermediate System to Intermediate System routing protocol as defined in RFC 1195.

Currently it (partially) supports the packaging/encoding requirements of the following RFCs: * RFC 1195 (only the TCP/IP related part) * RFC 3358 (optional checksums) * RFC 5301 (dynamic hostname extension) * RFC 5302 (domain-wide prefix distribution) * RFC 5303 (three-way handshake) * RFC 5304 (cryptographic authentication) * RFC 5308 (routing IPv6 with IS-IS)

TODO:

• packet relations (requests, responses)
• support for recent RFCs: * RFC 5305 (traffic engineering) * RFC 5307 (support for G-MPLS) * RFC 5310 (generic cryptographic authentication) * RFC 5316 (inter-AS MPLS and G-MPLS TE)

class scapy.contrib.isis.ISIS_AreaIdField(name, default, length_from)

Bases: scapy.fields.Field

addfield(pkt, s, val)

Add an internal value to a string

Copy the network representation of field val (belonging to layer pkt) to the raw string packet s, and return the new string packet.

getfield(pkt, s)

Extract an internal value from a string

Extract from the raw packet s the field value belonging to layer pkt.

Returns a two-element list, first the raw packet string after having removed the extracted field, second the extracted field itself in internal representation.

i2len(pkt, x)

Convert internal value to a length usable by a FieldLenField

i2m(pkt, x)

Convert internal value to machine value

length_from

m2i(pkt, x)

Convert machine value to internal value

randval()

Return a volatile object whose value is both random and suitable for this field
