Hi,
What i try is very simple but...won't work (i already read the archive with out
succes):
In RIP or EIGRP on a router there is two route (100.1.0.0/16 and 100.1.0.0/24)
I want to send ONLY the 100.10.0.0/16 to an other router.
I would like to know how to do with access-list and prefix-list (if possible).
rip/eigrp 1
distribute-list .... out serial 0
distribute-list prefix .... out serial 0
And mainly how to configure access and prefix list ?
Thank's a lot
