The messages indicate that you are running BGP, that you have two BGP neighbors, and that both BGP neighbors closed their BGP session and then opened new BGP sessions. Perhaps you should look on those neighbors to determine why they closed the BGP session.
It seems very odd to have BGP neighbors with IP addresses in the 169.254 network. Are you doing this intentionally?

The VRF aware BGP translate-update feature enables multicast forwarding on those customer-edge (CE) devices, whichhaveanolderversion of Ciscosoftware thatdoesnotsupport multicast BGP(mBGP) routing. The provider-edge (PE) devices establish a virtual routing and forwarding (VRF) session with the neighbor CE devices, and configure the translate-update feature under an IPv4/IPv6 VRF address family. The PE devices translate the updates from unicast to multicast on CE devices and put them as multicast updates in the Border Gateway Protocol (BGP) VRF routing table of the PE devices for processing.
