i have two cisco 1751 routers connected by isdn using EIGRP . The problem is no neighborship established between them and so eigrp not working
here is sample of show ip eigrp neighbor
H Address Interface Hold uptime SRTT RTO Q Seq
(sec) Cnt Num
0 20.0.0.81 bri0/0 14 00:01:17 1 5000 1 0
here is also part of debug eigrp neighbors command
%dual-5-NBRCHANGE: IP-EIGRP(0) 1: Neighbor 20.0.0.81 (bri0/0) is down: retry limit exceeded
note : no physical problem in the line (crc,frame,...) and i issued successfull ping from both sides with datagram 100 and 1500 .
