I'd begin with checking the K-Values match on both sides... Router#show ip protocols
Routing Protocol is "eigrp 100 100" Outgoing update filter list for all interfaces is not set Incoming update filter list for all interfaces is not set Default networks flagged in outgoing updates Default networks accepted from incoming updates EIGRP metric weight K1=1, K2=0, K3=1, K4=0, K5=0 <========= K-Values EIGRP maximum hopcount 100 EIGRP maximum metric variance 1 Redistributing: eigrp 100 100 EIGRP NSF-aware route hold timer is 240s Automatic network summarization is in effect Maximum path: 4 Routing for Networks: Routing Information Sources: Gateway Distance Last Update Distance: internal 90 external 170 Mark. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Mohammed Dado Sent: 18 October 2008 20:06 To: cisco-nsp@puck.nether.net Subject: [c-nsp] EIGRP routing failure Dears, We're configuring EIGRP on both sides, customer and ISP. The customer router are dumping the following logs.
