Problems establishing neighbor adjacency across ISDN when running EIGRP

Eamon.Moran

Level 1

The remote site cannot establish EIGRP neighbor adjacency across the ISDN to the central site even though the central site can. Sample config of the central site and remote site attached. Any idea what is wrong?

Central site

You need to add the keyword 'broadcast' to the outgoing dialer-maps as well.

For the remote side, this is accomplished. Thus the EIGRP updates come in to the central site as you described, in the other directions they are blocked.
