Python Prefix.pack Examples

Example #1

File: bgp.py Project: rnts08/exabgp

	def pack (self,addpath):
		if addpath:
			path_info = self.path_info.pack()
		else:
			path_info = ''

		if self.has_label():
			length = len(self.labels)*8 + len(self.rd)*8 + self.mask
			return path_info + chr(length) + self.labels.pack() + self.rd.pack() + self.packed[:mask_to_bytes[self.mask]]
		else:
			return path_info + Prefix.pack(self)
