EIGRP adjacency Flapping
Dears,
I configured a partial frame relay between three routers (R1, R2 & R3) with R2 as a HUB and R1 & R3 the spokes.
The L2 configuration for mapping the DLCI is working fine and I can ping all the interfaces with broadcast keywork added in the mapping statement.
The problem is we I configured the EIGRP AS 100 between them the adjacency come up, but I always got the following error in R3 ( the spoke) mentioning that the other Spoke’s IP address is not down.!!!!!
May someone explain what is the reason for this flapping???
