I'm having a strange problem with OpenVZ that is manifesting itself in strange ways.
Network set up is each HN has two NICs, one on 74.201.36.0/26, the other on 74.201.37.0/26. All VEs are in 74.201.38.0 or 74.201.39.0 and advertized as /32 entities via Quagga and RIPD.
The problem is that from within a VE, I can ping one interface on a host on the LANK, say 74.201.36.1, but not the other NIC from the other network on the same host (ie., 74.201.37.1). This is strange. The one I can ping is the one that is the preferred route in Quagga (ie., if 36.0). The one I can't ping is on the other LAN.
I've ruled out hardware issues because it randomly occurs across our network. Also,
I have this with several kernels, and even the most recent (and most recent vzctl). In /etc/vz/vz.conf I've changed VE_NEIGHBOR_DEVS from none, detect and all with no difference. The VE is announced via arp over both NICs.
Any help would be greatly appreciated.

DIAGNOSTICS BELOW:
ip route l from within the ve:
[root@vps6049 /]# ip route l
169.254.0.0/16 dev venet0 scope link
default dev venet0 scope link
ip route l from the HN:
[root@web2 ~]# ip route l
