[FROG] EIGRP: neighbor configuration validation error

[Amol Lad]

Hi,

I'm getting below error when trying to setup EIGRP neighbor. I initially suspected it could be because of /32 prefix but same problem comes with /24 network also.

FRR(config)# router eigrp 123
FRR(config-router)# network 10.0.0.254/32
FRR(config-router)# neighbor 10.0.0.1
% Configuration failed: validation error.

Please check the logs for more details.
FRR(config-router)#

Syslog output:
warning 2035-03-29T19:10:55+00:00 eigrpd: [EC 100663331] nb_callback_configuration: error processing configuration change: error [internal inconsistency] event [validate] operation [create] xpath [/frr-eigrpd:eigrpd/instance[asn='65000'][vrf='default']/neighbor[.='10.0.0.1']]
warning 2035-03-29T19:10:55+00:00 eigrpd: [EC 100663337] nb_candidate_commit_prepare: failed to validate candidate configuration

I'm using FRR 7.4 and libyang 1.0.167

Please advise.
Thanks
Amol
