#DISTRIBUTE LIST 1/3/2009 1:34 PM#


distribute-list in:

-> To filter networks recieved in updates , use the "distribute-lists in"
commnad in appropriate config mode .


USAGE GUIDELINES:

-> This command must specify either an access list or a map-tag name of a route-map
The route-map is supported for OSPF and EIGRP

-> ospf routes cannot be filetered from entering the ospf db . if you use this
command for ospf, it only filters routes from the routing table , it does not
prevent link-state packets from being propogated




distribute-list out :

-> To suppress networks from being advertised in updates, use the "distribute-list out"
command in the appropriate configuration mode .

-> When networks are redistributed , a routing process name can be specified as an
optional trailing argument to the distribute-list command

-> Specifying this option causes the access list to be applied to only those
routes derived from the specified routing process

-> After the process-specific access list is applied, any access-list specified
by a distribute-list commnad without a process name argument will be applied

-> Addresses not specified in the distribute-list command will not be advertised
commnad will not be advertised in outgoing routing updates .
