After upgrading from 12.4(15)T13 to 15.2(4)M3 we have an EIGRP one-way peering condition. The Hub sees the remote, but not vice-versa. The condition can be temporarily resolved by deleting the tunnel from the configuration and then re-adding it. After about a day, the one-way condition returns. A reboot does not resolve the issue. Booting back to T13 code also resolves.
Hardware is 7206VXR (NPE-G2) on both Hub and Spoke.
Has anyone seen this condition or possibly have a bugID to reference?
Do you see one way neighbor on ipsec, or routing protocol? Does it impact traffic? This seems to be new. I just did a bug scrub for my customer against the code. There are couple critical IPSec bugs, but I don't recall seen this DMVPN issue. Please open a case with TAC to track the bug.
