If the hub (r1) and spokes (r2,and r3) are on ospf network, and hub is also connected through ISDN to another router (r4) running rip. Now, let say I want to redistribute ospf routes to rip domain, making my hub router ASBR. r4 would obviously receive the ospf (loopback routes) as /32. Because of the /32 routes the ISDN link would keep coming up.--- On Fri 11/28, Brian Dennis < bdennis@internetworkexpert.com > wrote:

ld the best choice to get ridof /32 routes since they can create a problem for the ISDN between the hubrouter and the other end connected to some other router. I have seen theseissues when I practiced some labs from IPexpert, but never got any goodanswer.Regards,Ahmed.--- On Fri 11/28, Brian Dennis < bdennis@internetworkexpert.com > wrote:From: Brian Dennis [mailto: bdennis@internetworkexpert.com]To: Paul.Casey@o2.com, ccielab@groupstudy.comDate: Fri, 28 Nov 2003 16:28:25 -0800Subject: RE: os then the cost from the hub to the other spoke.Brian Dennis, CCIE #2210 (R&S/ISP-Dial/Security)bdennis@internetworkexpert.com Toll Free: 877-224-8987Direct: 775-745-6404 (Outside the US and Canada)Internetwork Expert, Inc.http://www.InternetworkExpert.com-----Original Message-----From: Casey, Paul (6822) [mailto:Paul.Casey@o2.com] Sent: Friday, November 28, 2003 3:22 PMTo: 'ccielab@groupstudy.com'Cc: 'Brian Dennis'Subject: RE: ospf network point-to-multipointBrian,What are the!
