count = 0
class ipmininet.router.config.zebra.AccessListEntry(prefix, action='permit')

Bases: object

A zebra access-list entry

Parameters:
  • prefix – The ip_interface prefix for that ACL entry
  • action – Wether that prefix belongs to the ACL (PERMIT) or not (DENY)

class ipmininet.router.config.zebra.RouteMap(name=None, match_policy='permit', match_cond=(), set_actions=(), call_action=None, exit_policy=None, order=10, proto=(), neighbor=(), direction='in')

Bases: object

Parameters:
  • name – The name of the route-map, defaulting to rm##

  • match_cond – Specify one or more conditions which must be matched if the entry is to be considered further
  • set_actions – Specify one or more actions to do if there is a match
  • call_action – call to an other route map
  • exit_policy – An entry may, optionally specify an alternative exit policy if the entry matched or of (action, [acl, acl, …]) tuples that will compose the route map
  • order – Priority of the route map compare to others
  • proto – The set of protocols to which this route-map applies
  • neighbor – List of peers this route map is applied to
  • direction – Direction of the routemap(in, out, both)
append_match_cond(match_conditions)
Returns:
append_set_action(set_actions)
Parameters:set_actions –
Returns:
count = 0
describe
