Hi Group,
After a sleepless night, I finally got the solution :o) In order to have IP connectivity I dont need a GRE tunnel to connect the two OSPF 0 areas. Its not needed to connect those two area 0, redistribution into the RIP and EIGRP is enough. I do also understand my second question, why OSPF area 0 has been enabled on the serial interfaces of R5 and R6. This is done in order to fulfill that task, that we can shutdown the ethernet on either R5 or R6 and still have full connectivity. In this case, no redistribution on R6 is needed. The same result can be reached with mutual redistribution on R5 and R6 from OSPF into EIGRP. I hope I got all that right :o) Von: prakash patel [mailto:[EMAIL PROTECTED] Gesendet: Freitag, 16.

DO EIGRP break when one link goes down ?..EIGRP (internal routes) has distance less than ospf Now put idea togehter _____ From: [EMAIL PROTECTED] To: [email protected] Date: Thu, 15 May 2008 22:47:28 +0200 Subject: [OSL | CCIE_RS] LAB21 OSPF Issue I really get stuck on some OSPF issue in LAB 21. One Task is to configure the Ethernet between R1 and R2 in OSPF area 0. But how does this Area 0 connect to the other Area 0 on R5R6R7? GRE Tunnel from R2 to R5? I cannot find a solution in the final config. Why is the Serial0/1/0 of R5 and the Serial of R6 in OSPF 0? To accomplish the taks that if the Ethernet of R5 or R6 fails we still have full connectivity? But this is done via redistribution, isnt it? I dont get it....can someone clarify that? How have you done these task? _____ Make Windows Vista more reliable and secure with Windows Vista Service Pack 1. Learn more. <http://www.windowsvista.com/SP1?WT.mc_id=hotmailvistasp1banner>
